This is one of only 700 Colt Hartford-English Dragoon revolvers manufactured between 1853 and 1857. These are among the rarest of the Colt "Horse Pistols" descended from the famous Colt Walker revolver. A large number of these revolvers remained unsold and were imported into the U.S. around the beginning of the Civil War. This example has a German silver blade front sight, "ADDRESS SAML COLT NEW YORK CITY" marked on the top barrel flat, London proofmarks on the barrel and cylinder, "COLTS/PATENT" marked on the left of the frame, The "MODEL U.S.M.R." and Texas Rangers and Comanche fight scene on the cylinder, and matching serial numbers visible on the wedge, barrel, frame, trigger guard, butt, and cylinder. The grip has been checkered.
