This Commercial production Colt Third Model Dragoon Revolver was manufactured c.1860. This late production revolver has the combination of square cylinder stops and rounded trigger guard that identify it as a Third Model Dragoon revolver. The six-shot cylinder is roll-engraved with the Ranger and Indian battle scene and "U.S. DRAGOONS/COLT'S PATENT" on either side of the cylinder. The "U.S. DRAGOONS" marking is a scarce variation, most Colt Dragoon cylinders were roll-engraved "U.S.M.R./COLTS PATENT". The part-round/part-octagon barrel has a nickel-silver front sight blade and the top barrel flat is roll-stamped: "- ADDRESS SAML COLT NEW-YORK CITY-" in one line reading toward the breech. "COLTS/PATENT" is stamped in two lines on the left side of the frame. The full serial number is stamped on the: (1) bottom of the barrel lug, (2) bottom of the frame, (3) trigger guard, (4) back strap and (5) cylinder. The loading lever is stamped with the partial serial number "9033". All of the visible serial numbers match. The revolver has a blued barrel and cylinder, casehardened loading lever, frame and hammer, and silver-plated brass back strap and trigger guard. The frame screws and protected areas of the wedge show traces of the fiery niter blue finish. The one-piece walnut grip has a high polish varnish finish.
