The Appeals Court determined that there was no error in denying the defendant’s motion for a required finding of not guilty, but felt “constrained to reverse” the defendant’s conviction of armed robbery while masked because the trial judge failed to exercise discretion in ruling on the defendant’s motion to exclude evidence of his prior convictions from being used to impeach the defendant’s credibility.
Commonwealth
v.
Knight,
At the close of the Commonwealth’s case, the prosecutor informed the judge and defense counsel that, if the defendant elected to testify, the Commonwealth would seek to introduce evidence of prior convictions to impeach the defendant’s credibility. See G. L. c. 233, §21. Defense counsel moved to have the convictions excluded on the ground that many of the prior convictions were for armed robbery and hence would be “very, very prejudicial.” Defense counsel suggested that the jurors would be influenced by them in considering the merits of the instant case.
The prosecutor stated that “under the recent case law, the Diaz case, I think it is, . . . even if [the convictions are] similar in nature it’s within the discretion of the judge to let them in.” Defense counsel agreed that use of the convictions to impeach was a ruling within the judge’s discretion.
After hearing argument from both counsel, the judge said, “It is my belief that we are dealing with a statute here, Section 21 of Chapter 233, and until the Legislature decides to change that statute, if they ever do, any attorney may introduce convictions which come under that statute either in a civil or a criminal proceeding. That would apply to the District Attorney or defense counsel . . . .” The judge denied the defendant’s motion and noted defense counsel’s objection. The defendant did not testify.
In reversing the conviction, the Appeals Court concluded that the judge’s “language . . . appears to be a ruling that the judge had no discretion to exclude the convictions.”
Commonwealth
v.
Knight,
Clearly, judges now have discretion to preclude the use of prior convictions to impeach a defendant’s credibility.

“In the
Chase
case, 372 Mass. [736,] 750 [1977], qualifying our decision in
Commonwealth
v.
West,
*195 The narrow question before us is whether the judge knew he had discretion and exercised it, or believed that his decision was compelled by the statute. We believe the record can support a conclusion that the judge knew he had discretion and exercised it in favor of the Commonwealth.
During the hearing on the motion, both counsel told the judge that a ruling either way was within his discretion, and each urged the judge to exercise discretion in favor of his position. Thus, this is not a case where the judge was unaware of his right to use discretion. Cf.
Commonwealth v. McFarland,
The defendant also alleges that he was denied due process because he was punished for exercising his right to a jury trial. Specifically, the defendant argues that, because his two codefendants who pleaded guilty were given shorter sentences, we should conclude that his sentence was unconstitutionally imposed. 3 The defendant has failed to provide us with the records and social histories which the probation department had compiled for the trial judge. Thus, this issue is not properly before us.
We observe, however, that on the limited record before us, it is clear that the judge based his sentences on an assessment of each defendant’s prior record, age, and character. It is also clear that the defendant had the most extensive prior criminal record of the men involved in this robbery. The judge also noted that the disparity in the prosecutor’s sentencing recommendation for Knight “had to do with [the defendant Knight’s] past criminal record.”
On the record before us there is no suggestion of vindictiveness on the part of the prosecutor or the judge, see
Longval
v.
Meachum,
Judgment of the Superior Court affirmed.
Notes
Of course, if a defendant moves to exclude evidence of prior convictions for impeachment purposes, the judge may condition such exclusion on the defendant’s agreement not to impeach the credibility of the Commonwealth witnesses by the use of prior convictions. We note, however, that, where a defendant seeks to impeach a witness on the ground of bias, see
Commonwealth
v.
Ferrara,
The judge could have concluded that, in light of the defendant’s prior convictions, the defendant could have had little, if any, incentive to tell the *196 truth, and in such circumstances, it would not deny the defendant a fair trial to permit the Commonwealth to impeach the defendant with his prior convictions.
“For any relief from the alleged severity of the sentences . . . recourse ... is to the Appellate Division of the Superior Court under G. L. c. 278, §§ 28A-28D.”
Commonwealth
v.
Whitehead,
There is no suggestion in the defendant’s brief that the sentence exceeded any presumptive sentencing guidelines. Further, the sentence is well within the statute governing masked armed robbery. See G. L. c. 265, § 17.
