  OPINION OF THE COURT
  BIGGS, Circuit Judge.
  On July 1, 1964, the appellant Hooks was found guilty by a jury on an indictment charging him in one count for the unlawful transfer of marihuana in violation of 26 U.S.C. § 4742(a), in two counts for the transporting and concealing of marihuana without paying tax in violation of 26 U.S.C. § 4744(a) (2), in two counts for the unlawful sale of heroin not from the original stamped package in violation of 26 U.S.C. § 4704(a) and in two counts for the unlawful sale of heroin without the prescribed order form in violation of 26 U.S.C. § 4705(a).,
  At trial, Hooks admitted that he had committed the acts charged in these counts of the indictment but alleged as his defense that he was in substance acting as a kind of de facto agent of the United States aiding Emrich, the federal narcotics agent who was in charge of the Pittsburgh office If Hooks’ story-had been accepted by the jury, an interesting question would have arisen as to whether or not conceivably he would have been within the exception authorizing non-registration of “(7) certain public officials” referred to in Leary v. United States, 395 U.S. 6, 17, 89 S.Ct. 1532, 23 L.Ed.2d 57 (1969). See note 19 cited to the text, at 18. See, e. g., 35 P. S. §§ 780-2(g), 780-4(q), and Bannister v. United States, 446 F.2d 1250 (3rd Cir. 1971). But the jury found Hooks guilty on each of the seven counts and he received substantial concurrent sentences on each. The judgments of conviction were affirmed by this court, 359 F.2d 584 (3 Cir. 1966). Hooks then brought this proceeding based on 28 U. S.C. § 2255, alleging that the judgments of conviction on Counts II and VIII, the marihuana counts, were void because the statutes on which they were based are “unconstitutional” and praying that the case be remanded to the district court with directions to grant him a new trial on the remaining five heroin or cocaine counts, viz., Counts I, III, IV, V and VI. Hooks takes the position that these five remaining counts are “inseparable” from Counts II and VIII and therefore are, so to speak, tainted by his allegedly illegal convictions on Counts I and VIII. Cf. note 2, supra. We do not perceive the force of this argument.
  There are four statutes involved here, the constitutionality of which cannot now be successfully attacked. They are, in the order of the indictment, Sections 4742(a), 4704(a), 4705(a) and 4744(a) (2), 26 U.S.C. The application of one of these sections, 4704(a), was before this court in United States v. Clark, 425 F.2d 827, 829-830 (1970), and was held constitutional, as was Section 4705(a) in respect to heroin by Minor v. United States, 396 U.S. 87, 90 S.Ct. 284, 24 L.Ed.2d 283 (1969). Section 4744(a) (2) prohibits the transfer or sale of marihuana without payment of the tax and provides that possession, combined with failure to produce the order form required by Section 4742(a) (2), is presumptive evidence of guilt. For the reasons stated in the opinion of the present writer in Bannister v. United States, supra, 446 F.2d at 1250, we hold that Leary is applicable to the conviction of Hooks on Counts II and VIII. In view of the testimony of Hooks that he was acting as a de facto United States narcotics agent, we remand the case to the district court to determine whether he waived knowingly his right to assert his complete defense to prosecution based on his privilege against self-incrimination, see Johnson v. Zerbst, 304 U.S. 458, 464, 58 S.Ct. 1019, 82 L.Ed. 1461 (1938) ; Fay v. Noia, 372 U.S. 391, 439, 83 S.Ct. 822, 9 L.Ed.2d 837 (1963); cf. Sanders v. United States, 373 U.S. 1, 18, 83 S.Ct. 1068, 10 L.Ed.2d 148 (1963).
  Other points raised by Hooks do not require discussion.
  The judgments of conviction on Counts I, III, IV, V, and VI will be affirmed, and the case will be remanded to the district court for further proceedings as to Counts II and VIII in accordance with this opinion.
  We thank our court-appointed counsel for his vigorous prosecution of his client’s claims.
  . There were eight counts. Count VII was duplicitous and was dismissed.
  . Although Hooks was released on probation on April 8, 1971, his case is not moot. Carafas v. LaValle, 391 U.S. 234, 88 S.Ct. 1556, 20 L.Ed.2d 554 (1968).
  . For the sake of clarity, we set out the substance of the pertinent statutes as follows:
  (1) 26 U.S.C. § Jf742(a), which prohibits the transfer of marihuana except pursuant to a written order of the transferee on a form issued in blank for that purpose by the Government;
  (2) 26 U.S.C. § 4744(a) (2), which prohibits transferees required to pay the tax on § 4742(a) transfers from transporting or concealing marihuana acquired or obtained without payment of the tax, and which provides that possession combined with failure to produce the order form required by § 4742 shall be presumptive evidence of guilt under this subsection ;
  (3) 26 U.S.C. § 4704(a), which prohibits the purchase and sale of narcotic drugs (in this case, heroin, and cocaine) except in the original stamped package, and which provides that the absence of appropriate taxpaid stamps from narcotic drugs shall be prima facie evidence of a violation of this subsection;
  (4) 26 U.S.C. § 4705(a), which prohibits the sale or exchange of narcotic drugs (in this case, heroin and cocaine) except pursuant to a written order of the transferee on a form issued in blank for that purpose by the Government.

  . See Trial Transcript, 162-170. See particularly 162-163, Hooks testifying on direct examination in his own defense, as follows:
  “Q. [W]hat did you [Hooks] do?
  “A. [H]e [Emrich] asked me about different narcotic sellers, and I told him that I knew them through my wife, but I hadn’t dealt with them, but maybe I could. And so, he and I, we discussed a plan to get me to get different drug pushers to meet him and sell him drugs. And, I told him that I would do this.”
  To give further specific instances of Hooks’ position would extend this opinion to too great a length. It is unquestionable that this record demonstrates that Hooks testified that he was acting in substance as a government agent and that this was his asserted defense.
