This commercial revolver was manufactured in 1859. The Third Model Dragoon can be quickly distinguished by its round trigger guard and rectangular cylinder stops. These were the most widely used of Colt's massive "horse pistols" that began with the famous Colt Walker. Around 10,500 Third Models were manufactured in 1851 to 1861. Many of these were used in the Old West and during the Civil War. The barrel has a German silver blade front sight and rear sight with two folding leafs (one absent folding leaf) and a fixed leaf at the center, partially obscuring the one-line New York address. The left of the frame is marked "COLTS/PATENT" in two lines. This example features a factory four-screw frame and back strap cut for use with a shoulder stock. The cylinder has the Indian fight scene and the "Model U.S.M.R." marking. Matching full and partial serial numbers visible on the barrel, frame, trigger guard, wedge, arbor pin, cylinder, and back strap. "8456" marked on the loading lever.

Very good, exhibiting period refurbished blue with mostly a smooth gray/brown patina with scattered very light pitting, and wear to the cylinder scene from period use with otherwise defined markings and edges in the metal. 60% original silver finish remains, strongest on the back strap and in protected areas of the trigger guard. Grips are also very good as revarnished with some moderate edge wear, some scuffing at the top corners, and a small re-glued section at the bottom rear corner of the right panel. Mechanically excellent. One absent folding rear sight leaf as mentioned above.
