“WAT” (Willian Andrew Thornton) inspected brass bow leg .44 mould with iron sprue cutter, for the Martially inspected 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. An inspectors initial “G” is stamped on the right leg. 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This mould is correct for all military inspected .44 calibre Colt 3rd Model Dragoon percussion revolvers, until it was superceded by an iron version.
