[1] The robbery with which defendants are charged occurred on 21 April 1979. Defendants contend that the court erred by admitting evidence of other unrelated crimes, but in this they are mistaken. The testimony as to crimes on 20 August 1978 and 27 January 1979 was elicited on cross-examination of defendant Boyd and was proper as impeachment. See 4 Strong’s N.C. Index 3d, Criminal Law §§ 86.1 and 86.5. The challenged testimony relating to 27 May 1979 was not evidence of a crime, and while the testimony objected to may have been irrelevant, we do not find that it was prejudicial.
[2] On 27 May 1979 officers stopped the vehicle which defendant Boyd was driving and in which defendant Milby was a passenger and arrested the defendants on a fugitive warrant. A *671search of defendant Boyd revealed a handgun, and a second handgun was found in the passenger seat where defendant Milby had been sitting. These guns were admitted into evidence and defendants assign error, arguing that no connection was established between the guns and the robbery five weeks earlier.
We agree with defendants that admission of these handguns was prejudicial error. There was no evidence that either gun matched the description given by the witness Juanita Fuller that one gun used in the robbery was ”a long, narrow gun” with “sort of a brass look.” This case is different from those in which a witness testifies that the object admitted into evidence is at least similar to that involved in the crime. See, e.g., State v. King, 287 N.C. 645, 215 S.E. 2d 540 (1975), death penalty vacated, 428 U.S. 903, 49 L.Ed. 2d 1209, 96 S.Ct. 3208 (1976); State v. Patterson, 284 N.C. 190, 200 S.E. 2d 16 (1973). See generally 1 Stansbury’s N.C. Evid. § 118 (Brandis rev. 1973). There was no
other evidence to connect these guns to the robbery for which defendants were on trial. “The general rule is that weapons may be admitted in evidence ‘where there is evidence tending to show that they were used in the commisson of a crime.”’ Id. at 194, 200 S.E. 2d 19 quoting State v. Wilson, 280 N.C. 674, 678, 187 S.E. 2d 22, 24 (1972). The question of whether the court’s error in admitting the guns into evidence was prejudicial is a close one, since there was substantial evidence that defendants were the prepetrators of the robbery. The State’s evidence was not so overwhelming, however, that we can say this error was harmless beyond a reasonable doubt. Accordingly, defendants must be granted a new trial.
We find no merit in defendants’ further assignments of error.
New trial.
