This ease arises out of a criminal prosecution for the sale of stimulant drugs in violation of 21 U.S.C. § 331 (q) (2). 1 The defendant, Patrick Emery, waived his right to a jury, and the trial was heard in the United States District Court for the District of Minnesota by The Honorable Gerald W. Heaney, United States Circuit Judge, sitting by designation. Throughout this case defendant has admitted his participation in the transaction in question. His defenses have been entrapment, undue delay on the part of the prosecution, and refusal to make a government informant available. At the conclusion of the trial defendant was found guilty as charged, and he was subsequently given an indeterminate sentence under the provisions of the Youthful Offenders Act. As grounds for reversal defendant argues the same three points that constituted his defense below: (1) that he was entrapped as a matter of law; (2) that he was prejudiced in presenting his defense by delay in prosecution; and (3) that he was denied access to a key government witness, thus making adequate preparation of his defense impossible. We find no merit in his contentions and the judgment of conviction is therefore affirmed.
The evidence adduced at the trial concerning the sale and its surrounding circumstances can be summarized briefly. On December 13, 1969 defendant sold some 600 tablets of dl-methamphetamine to Tom Liley, a paid government informant, and two agents of the United States Bureau of Narcotics and Dangerous Drugs. Defendant testified that he made the sale only after repeated entreaties from Tom Liley who allegedly needed the drugs to satisfy “some mafia types” who were “leaning on him.” Defendant acknowledged that before the sale he had not known Tom Liley well. Defendant claimed that his concern for Tom Liley’s safety stemmed from the fact that Liley's brother Pat was his roommate and best friend. The government informant, Tom Liley, testified that he may have solicited drugs from defendant more than once, but he could not remember how often, nor could he remember claiming that the “mafia” was “leaning” on him. Agents Muhlhauser and Walsh testified that they had never represented themselves to defendant as being members of the mafia. It is undisputed that defendant did not have the drugs in question in his apartment. Instead, defendant obtained the drugs from a third party and immediately resold them to Liley, Muhlhauser, and Walsh who were waiting outside. Defendant claims that he had never sold drugs before, that he made no profit on this sale, and that he acted merely as a go-between to help his roommate’s brother out of trouble. Finally, there was conflicting testimony concerning a meeting on December 15, 1969, at which defendant allegedly offered to make a second sale of drugs to Tom Liley and agent Muhlhauser.
Defendant contends that, on the facts stated above, he has established entrapment as a matter of law. To support this contention defendant analogizes his case to Sherman v. United States,
Defendant next contends that he was denied due process by the delay in bringing his prosecution.

The delays involved were approximately as follows : ten months from offense to the filing of charges, five and one-half months from complaint to indictment, and four months from indictment to trial.

Defendant argues that the government’s delay in pursuing the prosecution was deliberate and that defendant’s capacity to prepare a defense was thereby diminished. This claim must be distinguished from the situation in which a defendant’s capacity to prepare his defense is substantially impaired by a deliberate prosecutorial delay devised for the purpose of gaining a tactical advantage over the accused.
5
Here the initial prosecutorial delay was deliberate only in the sense that it was necessary to permit a far-reaching undercover investigation of the illegal drug traffic to reach completion.
6
Once that investigative operation was completed, charges against, defendant, as well as many others, were promptly filed. Similarly, the delay from accusation to trial was deliberate only in the sense that the government could have pursued defendant’s case

more rapidly. It is not seriously claimed here, nor was it proven at the trial level, that this pre-trial delay was a deliberate device on the part of the government to gain a tactical advantage over defendant.
7
The factor which is ultimately determinative of this issue, however, is that defendant has not succeeded in establishing any actual, substantial prejudice that resulted from the prosecutorial delay. The only showing of actual prejudice we have before us is defendant’s bare claim of faded memory. Defendant would have us follow Ross v. United States,
Defendant’s final contention is that he was deprived of due process by the prosecution’s failure to make Tom Liley, the government informant, available during the preparation of defendant’s defense. It is true that in appropriate circumstances the government must disclose the identity of unknown informants. Roviaro v. United States,
The judgment of conviction is affirmed.

. The scope of this investigation is evidenced by the number of cases that have come before us arising out of the same government effort.
See, e. g.,
United States v. Simon,
. Defendant’s argument assumes that once actual prejudice due to delay is shown the burden is then cast upon the government to justify the delay. Appellant’s Brief at 8. Since we find that defendant failed to demonstrate actual prejudice it is unnecessary for us to decide the extent and appropriate allocation of the burden.
