Manufactured c. 1873-1880 as an original cartridge gun, this is one of the more desirable variations of Colt's early pocket size "cartridge conversion" revolvers. Often termed the "solid barrel type", approximately 3,500 of these were made new by Colt as cartridge guns, while approximately 6,500 were conversions of the Model 1849 Pocket. The 3 1/2 inch round barrel has no provision for ejector or loading lever, and the percussion hammer is factory modified to fire rimfire cartridges. The two-line Colt address is marked on top of the barrel, "1871" and "1872" patent dates on the left of the frame, and "36 CAL" on the left of the trigger guard. All visible numbers are matching.

Exceptionally fine, retains 60% plus of the bright original high polish blue finish, 95% plus of the vibrant original case colors, and 40% plus of the original silver plating with the balance having thinned to mostly a smooth grey patina or attractively aged brass. The grip is very fine with some scattered minor handling marks and retaining most of the varnish. Mechanically excellent.
