Manufactured on order for the British Government, this is a Colt Government Model semi-automatic pistol which has passed through the London proof house; London "crown/V" and "crown/GP" proofs are present, as well as a martial "broad arrow" stamp on the left side of the frame ahead of the slide stop, "crown/G2/A" below the magazine catch, and "crossed pennants" stamps on the left rear of the slide, left side of the frame, and the left side of the barrel lug. The chamber hood is properly grooved for a .455 rimmed cartridge, and the two-tone pinned base magazine with another "pennant" proof "J.J" is stamped on the left side of the frame next to the trigger guard, and the two-tone magazine is correctly marked "CAL . 455/ELEY" on the pinned lanyard ring base.

Fine, with 50% of the original blue finish, showing areas of brown patina, bright edge wear, a number of scratches and dents, especially on the slide, and a small amount of pitting concentrated around the muzzle and near the hammer. The barrel bushing is a replacement. The thumb safety and mainspring housing are both refinished. The grips are good, with numerous scattered dents and scuffs. Mechanically excellent.
