Manufactured between 1870 and 1890 and having produced approximately 6,500 this was the first single shot pistol produced by Colt after they purchased the patent rights from National Arms Co. German silver half-moon front sight and hammer notch rear sight. The top of the matching serialized barrel is marked "COLT'S PT.F.A. MFG. Co./HARTFORD CT. U.S.A." followed by " No1" flanked by Maltese crosses. The serial number is marked on the butt and remarked to match on the bottom of the barrel. The frame has light scroll engraving with a checkered spur trigger and hammer. The grip area is iron, with shallow checkering on the sides, and deep sharp checkering on the back strap.

Very good as partially refinished,(the barrel), which retains 95% nickel finish with a couple small areas of minor pitting under the finish, a small area of flaking and pitting on the left side, and some flaking around the front sight. The frame shows minor pitting on the left side and a gray patina overall. The barrel hinge is a bit loose, otherwise the mechanics are fine. Markings are clear.
