Manufactured circa 1870-1890. Blade front and hammer notch rear sights, with the top of the barrel marked "COLT'S PT.F.A. MFG. Co/HARTFORD CT. U.S.A." followed by " No1" flanked by Maltese crosses and the matching serial number on the underside. Light scroll engraving on the sides of the frame with a burst design ahead of the hammer and scrollwork behind. The underside of the barrel bears a set of tiny "crown/GP" and "crown/V" stamps, with a small "C" present on the underside of the frame just ahead of the trigger. The crown stamps are the standard markings of the London Proof House, and the "C" marking was introduced by the Colt London Agency, which was having trouble with stateside agents trying to undercut them on the British market. With checkering on the hammer, trigger, and in panels on the grip. Includes a leather wrapped, fitted case and one .41 RF cartridge.
