To the cashier and night cook of the Dragon Inn Restaurant in Dorchester the defendant Johnson had become a familiar face. He had robbed the Dragon Inn five times and had attempted a sixth robbery within a four-month period. Shot and apprehended during the last visit, the defendant was convicted on five indictments of armed robbery and one indictment of armed assault with the intent to commit robbery. On his appeal Johnson protests that he was not armed on the sixth raid on the Dragon Inn’s cash register; that the judge imposed a vindictively harsh sentence; and that veiled references by prosecution witnesses to previous arrests of the defendant were inadequately neutralized. We affirm.
1. Whether the defendant was armed with a dangerous weapon on the occasion of the last assault. On the first four occasions that the Dragon Inn was held up, the robber, who was identified as the defendant, 1 brandished a firearm. On the fifth occasion, which occurred at 9:30 p.m. on April 30,1987, the robber appeared to be armed in that he had his hand in his left jacket pocket, held up about waist high, pointing away from him. He demanded money and received a little over $30. Later that night, at 10:45 p.m., the robber turned up again, similarly suggested a weapon in his pocket and demanded “all the money.” After the earlier episode, the cashier, Robert Cheung, had called his landlord, Thomas Williams. Accompanied by his son, Williams entered the restaurant while the second holdup of the night was under way. Some struggle ensued, during the course of which the younger Williams shot and wounded the defendant.
No firearm was found on the defendant. Next to where he collapsed after having been shot, the police found a hairbrush. *748 That is the dangerous weapon with which the defendant stands convicted of having been armed when he attempted the aborted robbery. It was open to the jury to find that the hairbrush had spilled from Johnson’s pocket and that, when he attempted the holdup, he had grasped the hairbrush in his pocket so as to simulate a handgun. The defendant urges that a hairbrush cannot be the basis for a conviction of assault with intent to rob while armed with a dangerous weapon. G. L. c. 265, § 18(b).
It is not necessary that the object designated as a dangerous weapon be inherently dangerous, so long as that object, from the perspective of the victim, reasonably appears capable of inflicting bodily harm, and the accused intends the victim to be intimidated.
Commonwealth
v.
Tarrant,
The concurring Justice in
Howard
(O’Connor, J.), envisioned circumstances uncomfortably close to those we now consider in illustrating his skepticism about the object versus part-of-the-body differentiation. That standard, he observed, “distinguish[es] between a statement plus a finger in a pocket and a statement plus a pocket comb or a pen.”
Id.
at 617. Yet there may be sound ground for fitting seemingly innocuous objects within the term “dangerous weapon” when that is how they are reasonably perceived. One of the reasons that an offense is aggravated if committed while armed with a dangerous weapon is the potential for sudden and violent reaction when objects are used in a way which makes a person appear
*749
to be armed.
Commonwealth
v.
Slaney,
This case handsomely illustrates that it is not just high altitude theory to suppose that an object which is dangerous or, as used, looks dangerous may ignite violence and harm. 2 Reasonable apprehension that the defendant Johnson was armed with a gun, as he had been on previous occasions, provoked Williams to produce his own weapon and to shoot Johnson, as well as to cause a melee and gunfire in a restaurant during business hours. Not only did the hairbrush produce an intended fear of harm, it fulfilled a dangerous weapon’s consequential tendency to provoke a breach of the peace. We think the jury could consider whether, in factual context, the hairbrush was a dangerous weapon. The defendant’s motion for a required finding of not guilty on the indictment arising out of the aborted robbery was, therefore, properly denied.
2. Vindictive sentencing. After the close of the evidence and final arguments of counsel there was a conference among the judge and counsel, some of it off the record. Immediately preceding his charge to the jury, the judge said:
“All right, I just want to put on the record that I made an offer to you, to your client relative to numbers six to nine. Six to nine is the number, and we’ll put this on the record, and your client’s rejected that.”
*750
When the jury returned verdicts of guilty on all six indictments, the judge imposed concurrent nine to fifteen year sentences. The defendant argues that imposition of the more severe sentences after the defendant chose to go the entire distance to jury verdicts suggests a “reasonable likelihood of vindictiveness,”

is discouraged. See

Letters
v.
Commonwealth,
Notably absent from this record is any expression by the judge of displeasure about Johnson’s failure to accept the sentence offered him or that consequences would follow from that failure. In those cases in which a more severe sentence following a rejected plea bargain has been held violative of the constitutional right to trial, the common thread has been the offer of a more lenient sentence in a “plea or else” form. See
United States
v.
Stockwell,
Here, as we have observed, there were no overtones of pressure. The sentences imposed were not harsh in terms of what the statutes permitted. They were less than the twenty to twenty-five years which the government recommended. During disposition proceedings the judge remarked that the defendant had committed repeated armed robberies; had been arrested; arraigned; and had robbed again. The reasons spelled out by the judge for his sentence pertained to the crimes and their effects, not to the defendant’s refusal to plead guilty. At the *752 time of sentencing, the judge had sentencing recommendations and probation reports available. We think the indicia of objective and legally acceptable sentencing criteria far outweigh the one indicator of vindictive sentencing, i.e., that the sentence imposed was greater than the one offered for a plea.
3. Possible innuendo from testimony about photographic identification. Johnson complains that the prosecution informed the jury by innuendo of his prior arrests. During the introduction of photographs of Johnson identified by the Dragon Inn’s cashier, the prosecutor and Detective Ingersoll made references to the effect that the photographs were mugshots. For example, when asked about the records in his custody, Ingersoll replied:
“A collection of arrest records, and accompanying those arrest records are police photographs. Those photographs are placed into books, and one complete wall is assigned to a collection of books.”
Some time later, defense counsel requested an instruction on the source of police photographs. The judge gave such an instruction while Detective Ingersoll was on the stand.
“Mr. Foreman, ladies and gentlemen of the jury, you heard this witness testify about photographs shown to Mr. Cheung. You shall draw no inference adverse to the defendant by virtue of the fact that the police had access to a photograph of him.
“There are many reasons why police departments have photographs of individuals. People apply for licenses. People apply for permits. People apply to become taxi drivers. People apply for all sorts of things. When they apply for those positions they must have their photographs taken.
“You shall draw no inference adverse to the defendant by virtue of the fact that there was a photograph of him available to the police department.”
*753
This instruction more than neutralized any innuendo from the possibly suggestive remarks of prosecution witnesses. Compare the similar, though less detailed, instructions approved in
Commonwealth
v.
Pullum,
Judgments affirmed.
Notes
The first identifications had been made from photo arrays. There were also in-court identifications by Robert Cheung, the cashier of the restaurant, and by Cheond Mui Chan, the cook.
