The Colt Model 1851 Navy was the second most popular of all the Colt percussion revolvers after only the Model 1849 Pocket, and 215,348 of these revolvers were manufactured in 1850-1873. This early revolver was manufactured in 1851 with the distinctive combination of the wedge under the screw and the square-back trigger guard that differentiates the Second Model from the other variations. It has a brass post front sight, "-ADDRESS SAML COLT NEW-YORK CITY-" on the top of the barrel, small "COLTS/PATENT" marking on the frame, the standard roll scene on the renumbered cylinder, and matching serial numbers on the loading lever, barrel, wedge, arbor pin, frame, grip straps, and back strap mortise of the grip (properly hand-written in black ink).

Very good with 75% plus replated silver remains on the grip frame, traces of original blue and casehardened finish, smooth gray patina on the balance, some patches of mild pitting, and general mild wear. The replacement back strap, trigger guard, and cylinder is renumbered to match gun. The markings are distinct. The refinished grip is very good aside from some mild edge wear and some light handling marks and scratches. Mechanically excellent. This is an attractive representative of one of the key variations of the famous Colt Model 1851 Navy.
