Manufactured in 1918 on order for the British Government, this is a Colt Government Model semi-automatic pistol outfitted with a .455 barrel and magazine, with a set of crossed pennant and broad arrow military stamps, "crown/G2/A", "crown/29/E" and "R.A.F." markings on the left side of the frame, "CALIBRE 455" on the right of the slide, along with the standard commercial markings. Fixed sights, with a long smooth trigger, wide checkered hammer, short grip safety, checkered grips, a two-tone magazine with "CAL.455/ELEY" marked lanyard base, and the proper "shelf" for the 455 case rim in the chamber hood. "K15" has been stamped on the top of the frame and the right side of the barrel lug, with "15K" on the underside of the slide. With a modern plastic case. This particular pistol can be seen in a full page spread (pg. 138) of Charles Clawson's "Colt .45 Service Pistols", where it is noted as having received service at Enfield Lock some time after initial acquisition.

Very fine, with 85% of the Enfield arsenal refurbished blue finish, showing some edge wear, scattered spotting and mild handling marks. The front sight shows signs that it was lowered and then touched up, with the top of the sight having a brown appearance. The grips are also very fine, with some light dents and scuffs, as well as some tool marks on the screws. Mechanically excellent.
