Aрpellant was convicted by a jury of assault with a deadly weapon and carrying a dangerоus weapon. 22 D.C.Code §§ 502 and 3204. On appeal, he has urged two points: 1) that the trial court misapplied the Luck rule on impeachment by a prior record, and 2) that he was denied a fair trial by the Government’s failure to conduct a fingerprint test on the gun involved in the alleged assault.
*257 I.
Under Luck v. United States, 121 U. S.App.D.C. 151,
Luck issues loomed large at trial in the present case, which was in large measure a “credibility contest” between appellant and the five other persons who were with him when the assault oсcurred. Defense counsel attacked the credibility of the Government’s witnesses by attempting tо show that they were conspiring to “frame” appellant and by bringing out prior inconsistent statemеnts to cast doubt on their veracity. From the transcript of the Luck hearing, it is apparent that this asрect of the case played a major role in the trial court’s concluding that one of appellant’s prior convictions could be introduced to impeach him. We agreе with the trial judge that the pitched battle on the credibility point heightens the importance of the Luck ruling. We disagree with his conclusion, however, that “[t]he ruling on the Luck matter has nothing to do with the Defendant’s right to take the stand.” While, as a matter of law, a defendant is always vouchsafed the constitutionаl right to testify regardless of the trial court’s grant or denial of his request for immunity from impeachment by his prior criminal record, as a practical matter an adverse ruling may effectively foreclose a defendant from taking the witness stand, lest his past misdeeds be his undoing at his present trial.
The priоr record which the trial judge held admissible was a 1954 housebreaking and larceny conviction. A man who steals is not necessarily a man who lies. A conviction for housebreaking, unlike one for pеrjury or false pretenses, sheds little light on the likelihood that the accused has lied on the stand. Thе prejudicial propensity of past convictions demands that as the probative valuе of a conviction lessens, greater caution be exercised in admitting it into evidence and that the trial judge explain to the jury the lesser weight to be given the conviction in evaluating the witnеss’ testimony. 1 Moreover, whatever the relevance of a recent housebreaking conviction, a housebreaking conviction which predated appellant’s instant trial by nearly fourteen years is of doubtful significance. The trial judge’s decision to admit the conviction was premised on his conclusion that the pertinent date for Luck considerаtions was 1965, when the appellant was released from prison. This misreads Luck and its progeny. 2 The prosecution is not permitted to introduce evidence showing a defendant’s reputation for dishonesty generally. An exception is made for prior convictions which are probative on lack of credibility, on the premise that as of the time of the act for which the defendant was convictеd, a jury had found him guilty of conduct which was illegal and which reflects on his trustworthiness.
We are not prepared, however, to say that the trial judge abused his discretion in the present case. Appellant’s trial counsel apparently agreed, *258 for he made no objection to the ruling. Moreover, the Luck ruling did not discourage the appellant from tеstifying. Indeed, defense counsel, not the Assistant United States Attorney, introduced the 1954 conviction, thereby softening its impact on the jury. 3 Therefore, we conclude that appellant’s conviction is not undercut by reversible error.

Due process is violated when the Government suppresses material evidence in its possession which is favorable to the defendant. Brady v. Maryland,
Affirmed.
