CUMMINGS, Circuit Judge.
In March 1977, defendant was indicted under 18 U.S.C. § 922(h) on the ground that he was a previously convicted felon who, on July 31, 1975, received a .38 caliber pistol which had previously been transported in interstate commerce. A jury found defendant guilty and he received a five-year sentence. Although defendant raises five issues in seeking a new trial, his most impressive point on appeal is that his constitutional rights were violated because he received a five-year sentence under 18 U.S.C. § 922(h) whereas the identical offense is proscribed by 18 U.S.C.App. § 1202(a), which carries a lesser penalty.
The essential facts that gave rise in his indictment under Section 922 can be stated briefly. On July 22, 1975, Russell Koch, Special Agent with the Treasury Department’s Bureau of Alcohol, Tobacco and Firearms, went in an undercover capacity to Carl’s Bar in Bellevue, Illinois, accompanied by an informant. Defendant was tending bar inside. Although the testimony at trial differed on who instigated the conversation, there was no dispute that Koch discussed with defendant a purchase of one or two firearms which were in defendant’s possession and that nine days later he sold Koch a .38 caliber revolver. The parties stipulated before trial that the revolver had been shipped in interstate commerce in 1948 and that the defendant in 1960 was convicted of a crime punishable by imprisonment for a term exceeding one year.1 He was tried and convicted under Section 922(h), which prohibits convicted felons from receiving firearms that have traveled in interstate commerce.
I. The Choice Between the 2-Year Sentence and the 5-Year Sentence
Because Section 1202 was part of a “last minute” amendment that was “hastily passed, with little discussion, no hearings, and no report” (United States v. Bass, 404 U.S. 336, 344, 92 S.Ct. 515, 520, 30 L.Ed.2d 488), it has posed several difficult problems of interpretation. See, e. g., United States v. Bass, supra; Stevens v. United States, 440 F.2d 144 (6th Cir. 1971). The problem posed here is that both 18 U.S.C.App. § 1202(a) and 18 U.S.C. § 922(h) prohibit one who has been convicted of a felony from receiving a firearm that previously traveled in interstate commerce but provide different penalties for that offense.
[629]*629Section 922(h), reenacted as part of Title IV- — State Firearms Control Assistance — of the Omnibus Crime Control and Safe Streets Act of 1968, provides:
“It shall be unlawful for any person— (1) who is under indictment for, or who has been convicted in any court of, a crime punishable by imprisonment for a term exceeding one year;
******
to receive any firearm or ammunition which has been shipped or transported in interstate commerce.”
Section 924(a) of the same statute provides for violations of Section 922 a maximum fine of $5,000 and a maximum imprisonment term of five years; defendant received the five-year maximum sentence.
18 U.S.C.App. § 1202(a), passed for the first time as Title VII — Unlawful Possession or Receipt of Firearms — of the same Omnibus Act, provides:
“Any person who—
(1) has been convicted by a court of the United States or of a State or any political subdivision thereof of a felony, * * and who receives, possesses, or transports in commerce or affecting commerce, after the date of enactment of this Act, any firearm shall be fined not more than $10,-000 or imprisoned for not more than two years, or both.”
Defendant’s argument is that two statutes that proscribe the same offense and require identical proof2 cannot subject an offender to different penalties. Apparently this argument has two dimensions, one based on statutory interpretation and the other based on potential constitutional impediments. We consider each in turn and conclude that it is impermissible to sentence a defendant for five years under Section 922(h) when he could receive only a two-year maximum sentence under Section 1202(a).
A. Statutory Interpretation
Section 922(h) had its origin in Section 2(f) of the Federal Firearms Act of 1938, 52 Stat. 1250, 1251. Section 5 of that statute made the penalty a $2,000 maximum fine or imprisonment for not more than five years, or both. 52 Stat. 1252. See 1968 U.S.Code Congressional and Administrative News pp. 2112, 2205, 2207 (1968). The statute was included as part of the Act that eventually was passed under the title of the Omnibus Crime Control and Safe Streets Act of 1968.
Although Section 922(h) was a part of that Act from its introduction in the House in 1967 through June of 1968 when the Act passed both Houses and was signed into law, Section 1202 was, as the Supreme Court described, a product of a last-minute amendment. See generally Stevens v. United States, 440 F.2d 144 (6th Cir. 1971). After the Act had passed the House and had been reported to the Senate by the Senate Committee on the Judiciary, on the day the Senate version of the Act passed the Senate Section 1202 was offered from the floor as an amendment by Senator Long. 114 Congressional Record 14775 (1968). No specific mention of Section 922 was made in the brief debate that followed, but one general reference to Title IV does appear. Senator Dodd asked whether Senator Long’s amendment was a substitute for Title IV and Senator Long replied (Id. at 14774):
“Mr. Long of Louisiana. This amendment would take nothing from the bill. I applaud what the committee did. This would add to the fine work the committee did in this area.”
After the Act passed the Senate, the House reconsidered it in light of the Senate’s changes before the bill, including both Sections 922(h) and 1202(a), was signed into law in June of 1968. In explaining Senator Long’s amendment to the House, Congress[630]*630man Machen said that “this provision is necessary to a coordinated attack on crime and also [is] a good complement to the gun control legislation contained in Title IV.” Id. at 16286.
This brief legislative history leaves a perplexing problem of statutory construction. While it could be argued that the legislators’ comments indicate that Congress intended the two titles to coexist, it is hard to imagine, and nothing in the history suggests, that the legislators if they were focusing upon these Sections could have considered Section 1202 a “good complement” to Section 922. Because we therefore find the legislative history inconclusive,3 our determination of what meaning to give to two inconsistent provisions in the same Act rests on the application of three general principles of statutory construction. First is the principle, recently reaffirmed in United States v. Bass, 404 U.S. 336, 347-349, 92 S.Ct. 515, 30 L.Ed.2d 488, and applied in a discussion of these same two titles of the hastily amended Omnibus Act, that ambiguity concerning the interpretation of criminal legislation should be resolved in favor of lenity.4 While this principle usually is applied to the interpretation of individual statutes whose phrasing is ambiguous, it also seems helpful when as here two separate parts of the same Act arguably contradict each other and therefore leave the intent of the legislators ambiguous. See 2A Sutherland’s Statutory Construction § 47.02.
To the extent that the individual sections of the Omnibus Act instead are regarded as separate enactments, a second principle of statutory construction comes into play: that a later-enacted statute can under certain circumstances serve as an implied repeal of an earlier statute. Applying this principle, it can be argued that Senator Long’s amendment — Section 1202(a) — is Congress’ last word on the issue of penalty because it was added to the bill after Section 922 and because it was first enacted in 1968 while Section 922 dates back 30 years earlier. While implied repeals are disfavored particularly in the absence of a manifest intent to repeal, the conflict between the two sections and the broad coverage of Section 1202 lend some support under these circumstances to the notion that the penalty in Section 1202 should predominate. See generally Radzanower v. Touche Ross & Co., 426 U.S. 148, 154, 96 S.Ct. 1989, 48 L.Ed.2d 540.
Although these first two principles cannot be applied to these facts without some difficulty, the third and in this case most important principle seems to apply with full force. That principle is that when a “serious doubt of constitutionality is raised, it is a cardinal principle that this Court will first ascertain whether a construction of the statute is fairly possible by which the question may be avoided.” Crowell v. Benson, 285 U.S. 22, 62, 52 S.Ct. 285, 296, 76 L.Ed. 598. See United States ex rel. [631]*631Attorney General v. Delaware & Hudson Co., 213 U.S. 366, 408, 29 S.Ct. 527, 53 L.Ed. 836. Because, as outlined in the next part of this opinion, the constitutionality of inconsistent penalties is open to serious question, this third principle, together with whatever persuasive force can be drawn from the first two principles, leads us to construe the Omnibus Act as limiting imprisonment to a maximum of two years for the offense of receiving a firearm by a convicted felon.5 Accord, United States v. Hairston, 437 F.Supp. 33 (N.D.Ill.1977).
B. Constitutional Issues Justice Black’s forceful dissenting opinion in Berra v. United States, 351 U.S. 131, 76 S.Ct. 685, 100 L.Ed. 1013, joined by Justice Douglas, touches on several important constitutional protections implicated by a prosecutor’s power to select one of two statutes that are identical except for their penalty provisions. Assuming that the protection against vague criminal legislation extends to the punishment provision (see United States v. Hairston, 437 F.Supp. 33, 35 (N.D.Ill.1977)), the statutes may be void for vagueness under the Fifth Amendment. As Justice Black suggested, “[a] basic principle of our criminal law is that the Government only prosecutes people for crimes under statutes passed by Congress which fairly and clearly define the conduct made criminal and the punishment which can be administered.” 351 U.S. at 139, 76 S.Ct. at 690. At least in the absence of published guidelines by the prosecutor (see Hutcherson v. United States, 120 U.S.App.D.C. 274, 281, 345 F.2d 964, 971 (1965)) (Bazelon, J., dissenting), certiorari denied, 382 U.S. 894, 86 S.Ct. 188, 15 L.Ed.2d 151, a second type of constitutional protection implicated is the due process and equal protection interest in avoiding excessive prosecutorial discretion and in obtaining equal justice. In Justice Black’s words (351 U.S. at 140, 76 S.Ct. at 691):
“The Government’s contention here also challenges our concept that all people must be treated alike under the law. This principle means that no different or higher punishment should be imposed upon one than upon another if the offense and the circumstances are the same.”
Tying these constitutional claims together are the basic concepts of separation of powers and delegation of authority. There is strong evidence that partially in order to avoid such vague penalties, excessive executive discretion and unequal justice, it is Congress’ constitutional responsibility in defining a criminal offense to affix a scheme of punishment. See United States v. Hudson, 7 Cranch 32, 11 U.S. 32, 34, 3 L.Ed. 259; Berra v. United States, 351 U.S. 131, 139-140, 76 S.Ct. 685, 100 L.Ed. 1013 (Black, J., dissenting); cf. United States v. Evans, 333 U.S. 483, 68 S.Ct. 634, 92 L.Ed. 823. Although, apart from Justice Black’s opinion in Berra we have found no Supreme Court opinions explicitly dealing with this precise question, the Court has emphasized that the legislature cannot shift its task of fixing punishment either to the courts (United States v. Evans, 333 U.S. 483, 486, 68 S.Ct. 634, 92 L.Ed. 823; cf. Giaccio v. Pennsylvania, 382 U.S. 399, 86 S.Ct. 518, 15 L.Ed.2d 447)6 or apparently to [632]*632administrative agencies, particularly in the absence of guidance or a clear delegation. See United States v. Grimaud, 220 U.S. 506, 516, 31 S.Ct. 480, 55 L.Ed. 563; see generally W. LaFave & A. Scott, Criminal Law 103 (1972); L. Jaffe, Judicial Control of Administrative Action 110 (1965).7 It is our conclusion that at best Congress would have no more power to delegate the selection of punishment to the Attorney General than it does to the courts or to administrative agencies.8 Because this statutory scheme, if interpreted to give meaning both to Sections 922 and 1202, would affix two separate and inconsistent punishments rather than one scheme of punishment (compare United States v. Evans, 333 U.S. 483, 68 S.Ct. 634, 92 L.Ed. 823), we have serious doubts about the constitutionality of that construction. See Berra v. United States, 351 U.S. 131, 139-140, 76 S.Ct. 685, 100 L.Ed. 1013 (Black, J., dissenting).
Consistent with the assertedly “settled rule” that the prosecutor can select which of two overlapping statutes to apply to a defendant (United States v. Ruggiero, 472 F.2d 599, 606 (2d Cir. 1973), certiorari denied, 412 U.S. 939, 93 S.Ct. 2772, 37 L.Ed.2d 398), the Government’s response to defendant’s challenge is to cite several cases stating that a defendant has no constitutional complaint if he is charged under a statute like Section 922 instead of one like Section 1202. E. g., Mauney v. United States, 454 F.2d 273 (6th Cir. 1972); United States v. Fournier, 483 F.2d 68 (5th Cir. 1973); United States v. Phillips, 522 F.2d 388 (8th Cir. 1975); United States v. Panetta, 436 F.Supp. 114, 129 n. 31 (E.D.Pa.1977); United States v. Raddatz, No. 77 CR 325 (N.D. Ill. Feb. 6, 1978). Contra, United States v. Hairston, 437 F.Supp. 33 (N.D.I11.1977).
Our reading of the cases cited by defendant, as well as those that have established the “settled rule” allowing prosecutorial choice, however, is that as applied to the choice between two statutes that have identical substantive elements they are either unpersuasive or inapplicable. Some of the opinions (e. g., United States v. Mauney, supra; Hutcherson v. United States, 120 U.S.App.D.C. 274, 278, 345 F.2d 964, 968 (1965) (Burger, J., concurring), certiorari denied, 382 U.S. 894, 86 S.Ct. 188, 15 L.Ed.2d 151) offer only an assertion that the issue was decided by the majority in Berra v. United States, supra. While Berra refused to disturb the conviction in a case apparently involving two identical statutes 9 with different penalties, the defendant on appeal in Berra contended only that the jury should have been given a lesser-in-[633]*633eluded offense instruction. Significantly, the Supreme Court majority expressly noted the question of the “validity of petitioner’s conviction and sentence, because of the assumed overlapping” but emphasized that “[no] such questions are presented here.” 351 U.S. at 135, 76 S.Ct. at 688. It was only Justice Black’s dissent that reached the issue, and he argued that the Court should have decided the propriety of the sentence rather than, as the Court apparently had done, require that the defendant raise the issue .in a Section 2255 proceeding. 351 U.S. at 137 n.4, 76 S.Ct. 685.
While the issue involved in this case thus was arguably present but not reached in Berra (except by the two Justices who would have vacated the sentence), in the other cases relied upon by the Government (e. g., United States v. Fournier, supra), this issue was not present. Those cases either are or rely without explanation upon cases in which the two overlapping statutes at issue did not have the same elements or standards of proof.10 This distinction, which was first suggested by the Court in United States v. Beacon Brass, 344 U.S. 43, 45, 73 S.Ct. 77, 97 L.Ed. 61, is significant because overlapping statutes and the resulting delegation of discretionary authority are unavoidable and thus a necessity in dealing with the wide variety of acts that Congress makes criminal, but there is no necessity for such a delegation when two statutes prohibit exactly the same conduct.11 Put another way, Congress cannot be said to have abandoned its responsibility to set a penalty when it sets different penalties in overlapping statutes because in doing so it has set a different penalty for each legally distinguishable offense, but it has abandoned that responsibility, when as here, different penalties are applied to statutes prohibiting identical acts. Cf. United States v. Evans, 333 U.S. 483, 68 S.Ct. 634, 92 L.Ed. 823; United States v. Petrillo, 332 U.S. 1, 7-8, 67 S.Ct. 1538, 91 L.Ed. 1877; Note, 109 U.Pa.L.Rev. 67, 95 (1960). Because we therefore find the reasoning of other circuits cited by the Government to be inapplicable, we decline to follow those cases here12 and are left with serious [634]*634doubts about the constitutionality of two statutes that provide different penalties for identical conduct.13 Fortunately we need not reach a final conclusion on these difficult constitutional questions because, having found a possible ambiguity when the Omnibus Act is read as a whole, we can give the Act a clearly constitutional reading by requiring that defendant’s sentencing be governed by Section 1202(a).
II. Objections to the Underlying Conviction
In seeking to have his conviction vacated as well as his sentence, defendant first argues that the indictment was fatally vague. Since the indictment itself referred to all the elements of the crime, described the firearm as “a .38 caliber pistol” and stated that it had been transported from Springfield, Massachusetts to St. Louis, Missouri, the contention that the indictment should have been dismissed is frivolous. See United States v. Slatton, 388 F.2d 676, 677 (6th Cir. 1968); United States v. Lent, 432 F.2d 440 (4th Cir. 1970); Federal Rule of Criminal Procedure 7(c)(1). As the defendant virtually admits in his brief (Br. 10), the Government’s bill of particulars, which described the weapon in further detail and stated the date of the shipment in interstate commerce, was sufficient to advise the defendant of the evidentiary details of the offense, even if the indictment did not. See United States v. Branan, 457 F.2d 1062, 1063-1064 (6th Cir. 1972). Defendant’s argument that the indictment was not sufficiently specific to provide double jeopardy protection is similarly merit-less in light of the fact that the entire record of a trial can be used in adjudicating a double jeopardy claim. See Russell v. United States, 369 U.S. 749, 764, 82 S.Ct. 1038, 8 L.Ed.2d 240; United States v. Henry, 504 F.2d 1335 (10th Cir. 1974).
The defendant also assails the trial court’s conduct at the voir dire on the ground that Judge Morgan should have inquired of prospective jurors whether they had previously served as jurors in criminal trials and whether defendant’s prior felony conviction might prejudice them against him. We have recently held that it is within a trial court’s discretion whether to ask the jurors about prior jury service. United States v. Staszcuk, 502 F.2d 875, 882 (7th Cir. 1975); 517 F.2d 53, 60 n.20 (7th Cir. 1975) (en banc), certiorari denied, 423 U.S. 837, 96 S.Ct. 65, 46 L.Ed.2d 56.
As to the district judge’s failure to interrogate the jurors about defendant’s prior felony, the voir dire shows that he first read the jurors the brief indictment which states that defendant had been “convicted on November 14, 1960, of a crime punishable by a prison term of one year.” Shortly thereafter, without expressly mentioning defendant’s prior felony, he asked the jurors seven questions with respect to their possible prejudice. Our reading of the transcript satisfies us that although asking at least some specific questions may be the better practice (see United States v. Dellinger, 472 F.2d 340 (7th Cir. 1972), certiorari denied, 410 U.S. 970, 93 S.Ct. 1443, 35 L.Ed.2d 706), this use of a series of questions following reference to defendant’s conviction cannot be termed an abuse of discretion. See United States v. Rojas, 537 F.2d 216, 219 (5th Cir. 1976), certiorari denied, 429 U.S. 1061, 97 S.Ct. 785, 50 L.Ed.2d 777; United States v. Brewer, 427 F.2d 409 (10th Cir. 1970); United States v. Windsor, 417 F.2d 1131 (4th Cir. 1969).14
[635]*635Defendant next claims that the trial court erred in denying defendant’s motion to strike the testimony of Special Agent Russell C. Koch of the Treasury Department’s Bureau of Alcohol, Tobacco and Firearms, when he failed to produce the handwritten reports of his meetings with defendant. The district judge apparently credited testimony at the voir dire that the typewritten summary produced through regular procedures contained all the material that had been contained in the original handwritten notes, and the Assistant United States Attorney advised the court that after the notes were typed, they were discarded. Therefore, under this Circuit’s decision in United States v. Harris, 542 F.2d 1283, 1292 (7th Cir. 1976), certiorari denied, 430 U.S. 934, 97 S.Ct. 1557, 51 L.Ed.2d 779, defendant received all that was required under the Jencks Act.
As in Harris, we recognize that all the circuits are not in accord with that holding, at least as it applies to the notes of F.B.I. agents. Although the majority view appears to be the one stated in our Harris opinion (see United States v. Martin, 565 F.2d 362 (5th Cir. 1978); United States v. Smaldone, 544 F.2d 456 (10th Cir. 1976), certiorari denied, 430 U.S. 967, 97 S.Ct. 1648, 52 L.Ed.2d 358; United States v. Hurst, 510 F.2d 1035, 1036 (6th Cir. 1976); United States v. Mechanic, 454 F.2d 849, 856 (8th Cir. 1971), certiorari denied, 406 U.S. 929, 92 S.Ct. 1765, 32 L.Ed.2d 131; United States v. Fioravanti, 412 F.2d 407 (3d Cir. 1969), certiorari denied, Panaccione v. U. S., 396 U.S. 837, 90 S.Ct. 97, 24 L.Ed.2d 88), the Ninth and District of Columbia Circuits have indicated that destruction of an agent’s handwritten notes might violate the Jencks Act. See United States v. Harris, 543 F.2d 1247 (9th Cir. 1976); United States v. Harrison, 173 U.S.App.D.C. 260, 524 F.2d 421 (1975). Even if we were to adopt the D.C. Circuit’s approach prospectively, however, no sanctions would be appropriate based on the lack of showing of negligence or bad faith and the considerable evidence of guilt adduced at trial. Id. at 273, 524 F.2d at 434. Although we therefore need not reach the Jencks Act question, apart from the interpretation of the statute we fail to understand why in the normal course these notes should not be retained so that, as Judge Sneed has written, “the question of whether an otherwise producible statement is useful for impeachment” can be left to the defendant instead of to the witness whom the defendant seeks to impeach. United States v. Johnson, 521 F.2d 1318 (9th Cir. 1975). Happily, we were advised at oral argument that agencies are adopting the practice of retaining the agents’ handwritten notes.15
Defendant next urges that the district court did not properly handle alleged jury exposure to newspaper publicity about this case. After the jury had retired to deliberate, defense counsel called the court’s attention to a Peoria newspaper article of that date stating that defendant had pleaded guilty to a murder charge in 1960 and had received a 25-year sentence. Pursuant to agreement with counsel, the district judge polled the jurors after they returned the guilty verdict, and all indicated they had not read or heard about that article.
After the verdict had been returned, two jurors told the trial judge that a third juror told them of a newspaper account of the case before jury deliberations had commenced. Consequently, the district judge conducted separate interviews with the jurors 'in camera. The juror who supposedly told other jurors about reading the newspa[636]*636per article advised Judge Morgan that she had not read any accounts of the trial until the day after the verdict was returned, and each juror also stated that there had been no discussion by any juror during the deliberations about any news accounts as to defendant, and that none of them knew what crime had been the basis of defendant’s previous felony conviction. It was the district court’s function, not ours, to assess the jurors’ credibility. Based thereon, he decided that no impropriety had occurred.16 This satisfied the procedure outlined in Margoles v. United States, 407 F.2d 727, 735 (7th Cir. 1969), certiorari denied, 396 U.S. 833, 90 S.Ct. 89, 24 L.Ed.2d 84.
While Rule 43(a) of the Federal Rules of Criminal Procedure did not require that defendant or his counsel be present during these interviews because the verdict already had been returned, defendant argues that his counsel’s presence should have been required in order to assure a vigorous inquiry. Because defendant did not show or apparently even seek a hearing to try to show prejudice, and in light of the overwhelming evidence of guilt, we agree with the Fifth Circuit that while inviting counsel would have been the better practice, the error was harmless. United States v. Parker, 549 F.2d 998, 1000 (5th Cir. 1977).
Finally, defendant submits that he was entrapped as a matter of law on the ground that the whole idea for the sale of a gun by defendant was implanted in his mind by informant Durine. Obviously, however, defendant was not entrapped into receiving the firearm, the crime with which he is charged, but rather was assertedly “entrapped” into selling the firearm, a crime with which he is not charged. It is worth noting that assuming the Government’s involvement in the sale might provide a theoretical basis for quashing the evidence obtained by the sale and thus rendering the firearm inadmissible (cf. Wong Sun v. United States, 371 U.S. 471, 83 S.Ct. 407, 9 L.Ed.2d 441; Hampton v. United States, 425 U.S. 484, 493, 96 S.Ct. 1646, 48 L.Ed.2d 113 (Powell, J., concurring)), that theory would be inapplicable here. As we read the record, the jury was presented with evidence that defendant initiated the sale rather than the Government agent, was instructed by the judge on entrapment (apparently without objection), and therefore must have chosen to believe Special Agent Koch’s version of the events.
The judgment below is vacated and the cause is remanded so that defendant may receive a maximum sentence of two years’ imprisonment instead of the five years previously imposed.
