Manufactured circa 1865 to 1870 with total production of an estimated 12,000 before being purchased by Colt in 1870. The top of the barrel has the one line address with the serial number on the underside. The assembly number "CG50" is stamped on the left frame side under the grip and on the right grip panel. The inside of the left grip is hand marked "CG/45" and the inside of the right grip is hand marked "CG/50". It has the standard scroll engraving and checkered grips. Blue finish with silver plated frame.

Fine, retains 40% plus of the original blue finish on the barrel and 30% of the original silver finish on the frame, with the balance of both having thinned to a smooth grey patina with crisp engraving. The grips are very fine with some scattered minor handling marks and crisp checkering. Mechanically excellent.
