A fine two-cavity brass bullet mold for casting round balls in .31 caliber, likely intended for pocket-sized percussion revolvers. Made of solid brass with crisp cavity edges and squared exterior faces, the piece shows balanced proportions and clean workmanship typical of early American mold-making. Its warm golden surface and evident use marks lend it appealing character consistent with 19th-century field or workshop use. Dimensions: Approx. 4.25 x 0.75 in.
