OPINION OF THE COURT
ROSENN, Circuit Judge.
In this case, we are called upon to determine several significant issues growing out of a civil rights action commenced by Michael Meyers, a Negro, charging Pennypack Woods Home Ownership Association with discrimination against Negroes in housing and membership.
I.
Pennypack Woods Home Ownership Association (“Pennypack” or “the Association”) is a non-profit Pennsylvania corporation organized in 1952 which owns and manages a community of a thousand separate housing units of one, two, and three-bedrooms in northeast Philadelphia. Each resident of Pennypack Woods is a member of and owns a one-thousandth undivided interest in the Association while Pennypack itself holds fee simple title to all the homes. A member of Pennypack enjoys perpetual use of a house pursuant to a “Home Security Policy” so long as he complies with Pennypack’s rules and regulations.
The demand for housing at Pennypack exceeds the supply and the Association has developed a complex system for filling vacancies. A member may transfer his Home Security Policy to certain close relatives, such as a parent or child, either by testamentary or inter vivos instrument, but such a member-resident may not otherwise “sell” his or her house. Units not transferred to relatives are allocated to Pennypack itself. First preference in disposing of two and three-bedroom units is given to current member-residents of Pennypack whose increased family size qualifies them for larger houses. Second preference is to children of current Pennypack members, thereby giv[897]*897ing children who have not received their parents’ house by transfer priority over outsiders in acquiring another Pennypack home. Those units which are filled neither by transfer to a relative nor by allocation to present Pennypack members or their children are then offered to persons who have been interviewed and placed on an approved waiting list. Any house still vacant would then, according to Pennypack’s rules, be offered to a list of outsiders not yet interviewed or approved.
On September 6, 1971, plaintiff applied by letter to Pennypack for a three-bedroom house for himself, his mother, and his three younger siblings. Pennypack replied that the list for three-bedroom homes was closed, which was in fact the case.1 In April 1972, Meyers once again wrote to Pennypack and asked to have his name placed on the waiting list and Pennypack again informed him that the list had been closed prior to his first application. In May 1972, Meyers’ counsel made a written demand that Meyers’ name be placed on the list ahead of persons applying after September 6, 1971. Pennypack refused to comply with Meyers’ demand.
On January 3, 1975, having failed in his efforts to secure Pennypack housing, Meyers brought an action against Pennypack and Marion Steinbronn, its president, in the United States District Court for the Eastern District of Pennsylvania alleging racial discrimination and seeking equitable relief, compensatory and punitive damages and attorney’s fees under the Civil Rights Act of 1866, 42 U.S.C. § 1982 (1970), and the Fair Housing Act of 1968, 42 U.S.C. § 3601 et seq. (1970). Following a non-jury trial, the district court found that Pennypack had never had a black member since its inception in 1952 although blacks comprise 34 percent of Philadelphia’s population. The court found, however, that
[t]he absence of black members of Pennypack is largely explained by the fact that few black persons have inquired about or applied for membership in Pennypack.
The district court further found that at all relevant times except for the summer of 1971 when he lived adjacent to Pennypack Woods,2 Meyers resided in the Bronx, New York, and that he had never sought housing in Philadelphia except for his application to Pennypack.3 Based on these facts, the court concluded that Meyers was a “tester” rather than a bona fide applicant for Pennypack housing.
The district court entered judgment for defendants on three grounds, any one of which, in the opinion of the district court, would alone have furnished sufficient support for the judgment: (1) that Meyers was not a bona fide applicant; (2) that both of Meyers’ claims were barred by the Statute of Limitations; and (3). that Meyers had failed to prove that defendants had discriminated against him because of his race. Meyers appeals from that judgment.
II. STANDING
The first issue we must consider is standing. Having found that Meyers was a “tester,” the district court held without citation that “[t]he absence of a good faith offer on the part of Meyers is a complete defense to his complaint under the Fair Housing Act of 1968 as well as the Civil [898]*898Rights Act of 1866.” We need not review the holding that a plaintiff’s lack of bona fides is a defense to a claim for relief under the Fair Housing Act4 since we hold in Section III, A, infra, that Meyers’ claim under that Act is time-barred. However, we are required to review the district court’s holding as it applies to sections 1981 and 1982.
The gist of the district court’s holding that Meyers’ status as a “tester” bars him from relief under sections 1981 and 1982 is, as wé understand it, that Meyers lacks the personal interest or stake in Pennypack’s policies which is required to give him standing to sue. See, e. g., Tileston v. Ullman, 318 U.S. 44, 63 S.Ct. 493, 87 L.Ed. 603 (1943).5 In appealing from this aspect of the district court’s decision, Meyers asserts that the court’s finding that he was a “tester” is.clearly erroneous but we need not review the court’s finding of fact. Even assuming arguendo that Meyers’ application to Pennypack was in fact motivated solely by his desire to test the legality of Pennypack’s policies, such a purpose is sufficient to confer standing. See, e. g., Smith v. YMCA of Montgomery, 462 F.2d 634, 645-46 (5th Cir. 1972). In Evers v. Dwyer, 358 U.S. 202, 79 S.Ct. 178, 3 L.Ed.2d 222 (1958) (per curiam), the Supreme Court held that a black plaintiff had standing to maintain a civil rights action even though his purpose in sitting in the white section of a segregated bus was to test the legality of the segregation. The Court reiterated the same principle nine years later in Pierson v. Ray, 386 U.S. 547, 558, 87 S.Ct. 1213, 18 L.Ed.2d 288 (1967). A group of clergymen from various Northern states, Pierson v. Ray, 352 F.2d 213, 215-16 (5th Cir. 1965), travelled to Jackson, Mississippi, and entered that city’s bus terminal “for the sole purpose of testing their rights to unsegregated public accommodations.” The Court held that
The petitioners had the right to use the waiting room of the Jackson bus terminal, and their deliberate exercise of that right in a peaceful, orderly, and inoffensive manner does not disqualify them from seeking damages under § 1983.
386 U.S. at 558, 87 S.Ct. at 1220 (footnote omitted). We therefore hold that Meyers has standing to maintain his action under § 1982.
III. STATUTE OF LIMITATIONS
A. The Fair Housing Act
Meyers contends that the district court erred in holding that his Fair Housing Act claim was time-barred by the 180 day limitation of 42 U.S.C. § 3612(a).6 According to Meyers, not only did the final refusal on the part of Pennypack occur as late as December 1975 but Pennypack’s discriminatory acts are also of a continuing nature. For these reasons, Meyers argues that his complaint filed on January 3, 1975, was timely.
[899]*899Pennypack, on the other hand, maintains that the violations are not continuing and that the last of the alleged discriminatory housing practices was the April 26, 1972, letter sent by Pennypack to Meyers — the final refusal by Pennypack to place Meyers' on the list. Pennypack contends that the complaint was untimely since it was filed more than two and a half years later. Two issues are thus raised: first, whether the alleged violation is a continuing one, and second, whether Pennypack’s conduct in December 1974 constituted a violation of the Act.
Turning to the first of these issues, we note that Meyers cites no authority for his argument that acts such as those alleged to have been committed by Pennypack may constitute a continuing violation for purposes of the 180 day limitation. Furthermore, all four of the eases which we could find seem to assume without discussion that a violation “occurfs]” and the 180 day peri-, od begins to run when an oral or written refusal to rent or sell takes place.7 We are aware, of course, of the employment discrimination eases dealing with the analogous 180 (formerly 90) day limitation period under Title VII of the Civil Rights Act of 19648 which hold that a discriminatory refusal to hire may constitute a continuing violation. See, e. g. Wetzel v. Liberty Mutual Ins. Co., 508 F.2d 239 (3d Cir.), cert. denied, 421 U.S. 1011, 95 S.Ct. 2415, 44 L.Ed.2d 679 (1975); Briggs v. Brown & Williamson Tobacco Corp., 414 F.Supp. 371 (E.D.Va.1976); Blank v. Sullivan & Cromwell, 418 F.Supp. 1 (S.D.N.Y.1975). Those cases, however, were class actions involving alleged patterns and practices of discrimination continuing to affect all members of the plaintiff class whereas the instant case concerns a discrete act of alleged discrimination against the individual plaintiff.9 Cf. Collins v. United Air Lines, Inc., 514 F.2d 594 (9th Cir. 1975); Loo v. Gerarge, 374 F.Supp. 1338, 1340 (D.Hawaii 1974). In the absence of contrary authority, we are persuaded that the alleged section 3604 violation against Meyers is not a continuing one for purposes of the 180 day limitation period of section 3612(a).
We must also reject Meyers’ contention that Pennypack’s conduct in December 1974 constituted either an independent violation of the Fair Housing Act or the final component of a single violation stretching back to Pennypack’s initial refusal to sell Meyers a house in September 1971. The conduct to which Meyers adverts consisted' of letters from Pennypack’s counsel to Meyers’ counsel rejecting the latter’s December 1974 demands for redress. If such futile attempts at settlement or negotiation by the alleged injured party were allowed to breathe life into a claim long dead, the 180 day limitation established by Congress would have little significance. Such a tactic, if permitted, would enable a victim of alleged discrimination to circumvent the statute of limitations merely by provoking his adversary into another refusal to sell or rent. We cannot believe that Congress intended the 180 day limitation of section 3612(a) to operate in such a fashion. Cf. United Air Lines, Inc. v. Evans, — U.S. —, 97 S.Ct. 1885, 52 L.Ed.2d 571 (1977). Accordingly, we hold that Meyers’ claim under the Fair Housing Act is time-barred.
B. The Civil Rights Act of 1866
The 180 day limitation of the Fair Housing Act has no application to Meyers’ claim under the Civil Rights Act of 1866, 42 U.S.C. sections 1981, 1982 (1970). Warren v. Norman Realty Co., 513 F.2d 730, 733 [900]*900(8th Cir.), cert. denied, 423 U.S. 855, 96 S.Ct. 105, 46 L.Ed.2d 81 (1975); Hickman v. Fincher, 483 F.2d 855 (4th Cir. 1973); cf. Young v. Int’l Tel. & Tel. Co., 438 F.2d 757 (3d Cir. 1971). Since Congress has provided no federal statute of limitations for sections 1981 and 1982 actions, we must apply “the limitation . . . which would be applicable in the courts of the state in which the federal court is sitting had an action seeking similar relief been brought under state law.” Polite v. Diehl, 507 F.2d 119, 122 (3d Cir. 1074) (en banc). See also Johnson v. Railway Express Agency, Inc., 421 U.S. 454, 462, 95 S.Ct. 1716, 44 L.Ed.2d 295 (1975); Ammlung v. City of Chester, 494 F.2d 811, 814 (3d Cir. 1974). The present action having been brought in federal court in Pennsylvania, our task is to determine which Pennsylvania statute of limitation would govern similar action under state law in a Pennsylvania state court. The decisions of the federal district courts of Pennsylvania are in conflict on this issue, some favoring Pennsylvania’s two year statute applicable to certain actions for personal injury,10 12 P.S. § 34,11 and others favoring Pennsylvania’s general six year statute,12 12 P.S. § 31.13 The resolution of this controversy requires that we understand both the essential nature of the federal claim and the operation of the various Pennsylvania statutes.
Turning first to the characterization of the federal claim, we observe that the decisions of the Supreme Court and of the other circuits do not reach any consensus. Actions under sections 1981 and 1982 have been analogized to state law actions for personal injury,14 breach of contract,15 trespass and wrongful appropriation of proper[901]*901ty,16 defamation and intentional infliction of mental distress,17 or to some unspecified tort.18 See Annot., State Statutes of Limitations As Affecting Federal Civil Rights Actions Under 42 U.S.C. § 1981, 29 A.L.R. Fed. 710 (1976). Furthermore, each aspect of a complaint under sections 1981 or 1982 may be given separate statute of limitations treatment depending on the nature of the specific act or acts complained of. Smith v. Olinkraft, Inc., 404 F.Supp. 861 (W.D.La.1975); cf. Polite v. Diehl, 507 F.2d 119, 122-23 (3d Cir. 1974) (en banc).
We begin our consideration of possible state law analogies to Meyers’ action by observing that the allegations of his complaint sound in tort, not in contract. Although the complaint may be read as alleging a wrongful refusal to enter into a contract, it cannot possibly be construed as alleging the breach of any existing contract. Meyers’ cause of action arises not from a breach of promise but from a breach of duty. It must therefore find its analogy in some sort of action in tort. Cf. Sewell v. Grand Lodge of Int’l Ass’n of Machinists & Aerospace Wrkrs., 445 F.2d 545, 548-50 (5th Cir. 1971), cert. denied, 404 U.S. 1024, 92 S.Ct. 674, 30 L.Ed.2d 674 (1972). The determination that the action sounds in tort is only the first step, however; we must identify the specific state tort most similar to the acts alleged in the complaint. We can best assess the similarity of the various state law torts to Meyers’ federal claim from three perspectives: (1) the defendant’s conduct, (2) the plaintiff’s injury, and (3) the relief requested.
Relying on the dictum in Curtis v. Loether, 415 U.S. 189, 195-96 n. 10, 94 S.Ct. 1005, 39 L.Ed.2d 260 (1974), Pennypack urges that for statute of limitations purposes we treat Meyers’ complaint as if it alleged defamation or intentional infliction of mental distress. Without expressing any opinion as to whether that analogy might be appropriate for other actions under sections 1981 or 1982 complaining of different sorts of conduct, we decline to adopt it in the case sub judice. Meyers’ complaint may peripherally encompass the emotional or psychic injury which he may have suffered, but its averments are directed to a specific concrete injury: Meyers wants to buy a house in Pennypack Woods and Pennypack wi]l not sell him one. Pennypack’s conduct bears little resemblance to defamation or to an intentional infliction of mental distress. Meyers’ injury is primarily tangible, not intangible; and Meyers wants both a house and damages for the deprivation he has endured. For these reasons, we do not believe that Meyers’ suit can be properly treated as an action for defamation or for intentional infliction of mental distress.
We are also not persuaded by Pennypack’s suggestion that Meyers’ action should be analogized to a state law action for invasion of privacy. Although an invasion of privacy also may produce mental anguish, the essence of the injury is an unreasonable interference in making know a person’s affairs to others or exhibiting his likeness to the public. See Restatement of Torts § 848; Hull v. Curtis Publishing Co., 182 Pa.Super. 86, 125 A.2d 644 (1956). On the other hand, the gravamen of the injury alleged here is the tortious refusal to contract for the sale of a house. Flowing from both injuries — the invasion of privacy and the refusal to enter into a contract — may be a painful mental reaction, but this commonality hardly affords a sufficient basis for equating the breach of duty in the two instances. Pennypack’s conduct bears little resemblance to an invasion of another’s privacy.
[902]*902Having concluded that Meyers’ actions cannot be equated with an action for defamation, for mental distress, or for invasion of privacy, we turn our attention to another group of torts recognized by Pennsylvania law — torts such as fraudulent interference with contractual rights 19 wrongful interference with another’s business,20 violation of seniority rights,21 and breach of an express trust.22 All these torts involve the wrongful interference with another’s financial, commercial, or business rights. A victim of one of these torts suffers not so much from an emotional or mental trauma as he does from the actual denial of his right to lawfully pursue his business, employment, or personal affairs. Meyers appears to complain of just such a denial.
To be sure, Meyers has also allegedly suffered injury to his “feelings” but the thrust of his complaint, cf. McCully-Smith, supra, is that Pennypack wrongfully interfered with and deprived him of his federally protected right to contract for the purchase of a home. We must therefore apply the statute of limitations which Pennsylvania courts apply to state law actions complaining of similar tortious conduct.
The Pennsylvania scheme of limitations is complex. The Act of March 12, 1713, 12 P.S. § 31, see note 13 supra, established inter alia a single six year limitation governing all actions in contract as well as all actions of trespass.23 The Act of June 24, 1895, 12 P.S. § 34, see note 9, supra, without reference, however, to the former act, provides a two year limitation on actions for personal injury not resulting in death. Faced with this incongruity, the Pennsylvania Supreme Court has held that the Act of 1895 repealed the Act of 1713 insofar as relevant but that the Act of 1713 still governs all actions in trespass not involving personal injury.24 See Walker v. Mummert, 394 Pa. 146, 146 A.2d 289 (1958); Helmig v. Rockwell Mfg. Co., supra, 389 Pa. 21, 131 A.2d at 626 n. 3, 628. Thus, Meyers’ action is governed by the general six year statute, section 31, unless it falls within the precise terms of the more limited two year statute, section 34.
Even without the benefit of the numerous cases on point, we would be inclined to conclude as a matter of statutory construction that Meyers’ claim does not come within the limited compass of section 34. First, that section by its terms applies only to “actions brought to recover damages” whereas Meyers seeks a broad range of equitable relief. See Jones v. United Gas Improvement Corp., 383 F.Supp. 420 (E.D. Pa.1975). Secondly, the statutory phrases “injury wrongfully done to the person, in cases where the injury does not result in death” expresses a limitation only on actions for bodily injury25 whereas Meyers’ claim is for tortious interference with his right to contract for the purchase of a house. See Jones, supra.
We need not base our decision on such considerations, however, since the case law is clear. In state law suits resembling Meyers’ action, both Pennsylvania courts and federal courts applying Pennsylvania law have uniformly applied the six year limita[903]*903tion of section 31.26 See McCully-Smith Assoc., supra, 358 F.Supp. at 332; Falsetti, supra, 249 F.Supp. at 972; Cooper, supra, 201 F.Supp. at 170 n. 3; Sherwin, supra, 18 F.R.D. at 194; Haefele v. Davis, 399 Pa. at 511, 160 A.2d at 714; Helmig, supra, 389 Pa. at 28 n. 3, 131 A.2d at 626 n. 3. Cf. Gainey v. Brotherhood of Rwy. and Steamship Clerks, 275 F.Supp. 292, 306 (E.D.Pa. 1967), aff’d, 406 F.2d 744 (3d Cir. 1968), cert. denied, 394 U.S. 998, 89 S.Ct. 1590, 22 L.Ed.2d 775 (1969). We therefore conclude that Meyers’ action under §§ 1981 and 1982 is not time-barred.27
IV.
We have determined that Meyers had standing to maintain his action and that his claim under the Civil Rights Act of 1866 was not time-barred. Nonetheless, we are unable at this time to review the district court’s judgment that plaintiff suffered no discrimination because the district court excluded two key witnesses offered by Meyers on the ground that they were not listed in plaintiff’s pretrial memorandum. Although a trial court’s ruling excluding evidence because of the failure of counsel to adhere to a pretrial order will not be disturbed on appeal absent a clear abuse of discretion, De Laval Turbine, Inc. v. West India Indus., Inc., 502 F.2d 259 (3d Cir. 1974); Moore v. Sylvania Elect. Prods., Inc., 454 F.2d 81 (3d Cir. 1972), we are constrained to conclude that the exclusion of these two witnesses did constitute such an abuse.
The district court had directed (1) that all discovery be completed by January 30,1976, (2) that plaintiff file his pretrial memorandum, including a list of his expected witnesses, by January 15, 1976, and (3) that defendant file its pretrial memorandum, including its expected witnesses, by February 2, 1976. Plaintiff timely filed his pretrial memorandum listing seven witnesses and on February 23, 1976, a pretrial conference was held and trial was scheduled for March 17, 1976. Three days later, February 26, 1976, plaintiff, evidently having learned of potential new fact witnesses, sent a letter to defendant’s counsel with copy to the trial judge informing him that he wished to supplement the pretrial memorandum with the names of the following witnesses whom plaintiff might call at trial:
Donald Sweeney
Mr. and Mrs. Morris Milgram
Custodian of Records of Pennypack
Woods Home Ownership Association
The letter concluded with the following invitation: “If you have any questions concerning the above, please do not hesitate to contact us.” Donald Sweeney was Penny-pack’s former president and then resided in [904]*904Pittsburgh, Pennsylvania. Milgram was a developer of integrated communities who lived in Green Belt Knoll adjacent to Pennypack. Defendant neither accepted the invitation of plaintiff’s counsel to contact him nor attempted to depose the new witnesses but by letter dated March 3, 1976, to the trial judge pleaded prejudice and surprise.
When the case was called for trial on March 17, plaintiff called Sweeney and Morris Milgram. According to counsel for Meyers, they would have testified that in past years Negroes had inquired or unsuccessfully applied for housing at Pennypack and that Pennypack had a reputation in the black community as an all white development in which Blacks could not buy homes.
Pennypack objected to testimony of these two witnesses because they had not been previously listed in the pretrial memorandum and because their testimony now came as a surprise and was prejudicial since defendant had not had the opportunity to depose them and ascertain in advance what they proposed to say. Plaintiff responded that his letter to defense counsel afforded him “every opportunity” but no request was ever made for information as to what the witnesses would testify.28 The trial judge sustained defendant’s objection and excluded the witnesses.
A reading of the district court’s opinion demonstrates how important such testimony might have been and how critical is its absence. The district court’s conclusion that Pennypack did not discriminate against Meyers was based in large measure on the premise that Pennypack’s policies had no discriminatory effect against Blacks in general. That conclusion was in turn predicated on the court’s finding of fact that the potentially significant statistical absence of black residents in Pennypack was not the result of discrimination but rather was a product of complete disinterest by Blacks in -residing in Pennypack. Evidence tending to prove that the absence of Blacks was not due to a lack of interest conceivably could have led the judge to conclude that Pennypack’s policies were intentionally discriminatory or, at least, discriminatory in their effect, and might ultimately have led to a judgment in Meyers’ favor. Given these facts, the question is whether the district court’s exclusion of Sweeney and Milgram constituted an abuse of discretion.
Decisions of this and other courts suggest the factors to be considered in resolving this question: bad faith on the part of the party seeking to call witnesses not listed in his pretrial memorandum; see Clark v. Pa. R.R. Co., 328 F.2d 591 (2d Cir. 1964), cert. denied, 377 U.S. 1006, 84 S.Ct. 1943, 12 L.Ed.2d 1054 (1965); ability of the party to have discovered the witnesses earlier, see Hunt v. Pa. R.R. Co., 41 F.R.D. 349 (E.D.Pa.1967); validity of the excuse offered by the party, Thompson v. Calmar Steamship Corp., 331 F.2d 657, 662 (3d Cir. 1964); willfulness of the party’s failure to comply with the court’s order, Taggart v. Vermont Transportation Co., 32 F.R.D. 587 (E.D.Pa.1963), aff’d 325 F.2d 1022 (3d Cir. 1964); the parties’ intent to mislead or confuse his adversary, Pakech v. American Export Isbrandtsen Lines, Inc., 69 F.R.D. 534 (E.D.Pa.1967); and finally, the importance of the excluded testimony, Clark, supra. Underlying the cases to which we have adverted are these basic considerations: (1) the prejudice or surprise in fact of the party against whom the excluded witnesses would have testified, (2) the ability of that party to cure the prejudice, (3) the extent to which waiver of the rule against calling unlisted witnesses would disrupt the orderly and efficient trial of the case or of other cases in the court, and (4) bad faith or [905]*905willfulness in failing to comply with the court’s order.
Applying these considerations in the instant case, we are constrained to conclude that the district court abused its discretion in excluding Sweeney and Milgram. Pennypack made no allegation and the district court made no finding that Meyers’ failure to include Sweeney and Milgram in his list of witnesses either in his original pretrial memorandum or in his amended pretrial memorandum of February 23 was a product of bad faith nor that Meyers’ failure to comply with the order was willful or intended to mislead or confuse Pennypack. The excuse offered by Meyers for his failure to list the witnesses was apparently a bona fide representation that he had not discovered them until after the pretrial memorandum was filed. We have recently held that the exclusion of critical evidence is an “extreme” sanction, Dudley v. South Jersey Metal, Inc., 555 F.2d 96, at 99 (3d Cir. 1977), not normally to be imposed absent a showing of willful deception or “flagrant disregard” of a court order by the proponent of the evidence. In the instant case, neither the district court not Penny-pack found or alleged such misconduct by Meyers. Id. In Dudley, supra, we recognized that counsel for the defendant had by his answers to certain interrogatories created confusion and uncertainty but we also observed that the plaintiff’s assertion of surprise and prejudice had to be viewed in the context of the plaintiff’s own failure to take any steps to clarify the facts.
The instant case presents a similar situation. The February 26 letter from Meyers’ counsel, even though it was written almost three weeks before the commencement of trial, may have complicated the trial preparation of his adversary but Pennypack’s counsel for his part made no attempt to simplify matters by responding to plaintiff’s offer to furnish information or by initiating further discovery.
Weighing against these factors were the alleged prejudice to Pennypack and the possible disruptive effect of waiving the rule. On examination, however, neither of these factors appears significant in this case. The possible prejudice to Pennypack was minimized not only by Pennypack’s familiarity at least with Sweeney, its former president, but by the sequence of events. The letter to which Pennypack objected so strenuously followed by only three days Meyers’ filing on his amended pretrial memorandum to which Pennypack voiced no objection. More importantly there remained after the letter was sent almost three weeks before trial. Yet Pennypack made no effort to depose or serve interrogatories on the new witnesses or even to request Meyers’ counsel to furnish additional information or written statements of the proposed testimony. We believe that in these circumstances Pennypack had some obligation to take steps to minimize its alleged prejudice and surprise. We are also persuaded that the orderly and efficient trial of other cases in the court and of this case in particular would not have been seriously impeded by the relaxation of the trial order. It would have been entirely appropriate for the district court to impose reasonable sanctions on Meyers for his failure to list the witnesses, but we believe a less drastic sanction, especially since it was a bench trial, should have been adopted — perhaps, an adjournment of a few days while Pennypack conducted discovery with costs taxed to Meyers. Dudley, supra, at 100.
For these reasons, we hold that the district court abused its discretion in excluding the testimony of Sweeney and Milgram. Since this is not a jury trial, it may be feasible simply to reopen the trial for additional testimony rather than to hold an entire new trial.29 We encourage the district court to consider this possibility.
V.
The judgment of the district court will be affirmed in part and reversed in part and [906]*906the case remanded for further proceedings not inconsistent with this opinion. Each party to bear his or its costs.
