.44 brass bow leg mould with iron sprue cutter, for the Colt 3rd Model Dragoon percussion revolvers. Bowleg mould, stamped “COLT’S / PATENT” with an apostrophe, on the top face of the “in the white” sprue-cutter, close to the hinge. The two cavities, are for a round ball, nearest the hinge pin and a pointed conical with a heel base and a narrow grease groove. The groove helps facilitate loading into the cylinder chamber. The locating pin is on the right leg. This mould is correct for all .44 calibre Colt 3rd Model Dragoon percussion revolvers, until it was superceded by an iron version.
