The Colt Model 1851 Navy was the second most popular of all the Colt percussion revolvers, after only the Model 1849 Pocket, with 215,348 of these revolvers 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 all matching visible serial numbers on the loading lever, barrel, frame, trigger guard, wedge, cylinder pin, cylinder, butt, and handwritten in black ink inside the grip mortise.
