Only an estimated 2,700 Second Model Dragoon revolvers were manufactured from 1850 to 1851 compared to 7,000 of the First Model Dragoons and 10,500 Third Model Dragoons. They are thus by far the rarest of the primary Colt Dragoon revolvers. The combination of rectangular cylinder stops and square-back brass trigger guard clearly identify the revolver as a Second Model Dragoon. The barrel has a German silver blade front sight and is marked "-ADDRESS SAMl COLT, NEW-YORK CITY" on the top flat. The loading lever has a vertical catch. "COLT'S/PATENT/U.S." stamped on the left of the frame. The cylinder has the Texas Ranger and Indian fight scene along with the "MODEL U.S.M.R./COLT'S PATENT" marking. Small single letter inspection marks are present on various components. Matching full and partial serial numbers are marked on the barrel, frame, trigger guard, back strap, loading lever, wedge, cylinder, and arbor pin. Each side of the grip has a script letter cartouche with "JCB" (Joseph C. Bragg) on the left and "WAT" (William A. Thornton) on the right. The U.S. contract Colt Dragoon revolvers were used primarily by the First and Second Dragoon Regiments and the Regiment of Mounted Riflemen.

Fine and well above average, retains 40% original blue finish on the barrel with smooth brown patina on the balance, numerous small dings around either side of the wedge, and defined edges and markings in the metal. The cylinder has turned to mostly a smooth brown patina with strong traces of original blue finish and an attractive distinct cylinder scene. The frame exhibits a smooth gray and brown patina with 30% of original case colors mostly visible on the rear of the recoil shield. Brass retains an attractive bright patina with some scattered small dings on the butt. Grip is also fine with rich oil finish, some scattered light scratches, numerous small dings on the butts, a crisp cartouche on the left and a clear cartouche on the right. Mechanically excellent. This fine attractive example of a desirable U.S. marked Colt Second Model Dragoon would make an excellent addition to any Colt or U.S. Martial collection!
