Manufactured in 1863. This revolver was subsequently nickel plated, probably by Hartley & Grahm, a well known outfitter of the time. The top of the barrel is marked with the one line New York address, "COLTS / PATENT" on the left side of the frame, and inspector letter stampings on both sides of the barrel lug, trigger guard, backstrap and cylinder. All serial numbers match including the wedge and the cylinder is roll engraved with the naval battle scene. The three screw frame is cut for a stock. Fitted with a smooth one piece grip with a very faint cartouche on each side.
