Appellant appeals from his conviction and sentence of possession of stolen government property, in violation of 18 U.S.C. § 641. We affirm.

Appellant complains that the court’s supplemental instructions were erroneous; that the court erred in refusing to grant a mistrial after the court excluded a government exhibit and related evidence; and finally that it was plain error for the court to omit instructions as to the effect of appellant’s character evidence. We find no error.

Judgment is affirmed.
