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 between 1850-1873. This early revolver was manufactured in 1850, the first year of production, and has the distinctive combination of the wedge under the screw and the squareback trigger guard that differentiates the Second Model from the other variations. It has a brass cone front sight, "-ADDRESS SAML COLT NEW-YORK CITY-" on the top of the barrel, "COLT'S/PATENT" marking on the left of the frame, the classic Naval Battle of Campeche roll scene on the cylinder, and matching serial numbers visible on the loading lever, barrel, frame, trigger guard, wedge, arbor pin, cylinder, and butt.

Very good plus with the cylinder retaining strong traces of dulled original blue finish and a mostly defined cylinder scene, smooth brown patina on the remaining iron surfaces and clear markings and edges in the metal. 70% original silver finish remains on the trigger guard and grip straps with some light flaking. Grip is very good with moderate edge wear on the left panel, crazing, and some scattered light scratches and handling marks. Mechanically fine. This is a desirable Colt Model 1851 Navy variation.
