Manufactured from 1863 to 1875. The top barrel flat is stamped with the 1858 patent date over the New York address over "NEW MODEL." The barrel and grip panels are numbered to the gun. Most of the major components are stamped with single letter sub-inspector marks including "D", "W", and "C." The revolver is fitted with smooth grips featuring a clear script cartouche on the left panel and "D" sub-inspector mark on the bottom of both panels.

Very fine. The revolver retains 80% plus bright original blue finish with the balance a smooth brown-gray patina. The hammer retains some strong original case colors. The grips are excellent showing some minor pressure dents with a crisp cartouche. Mechanically excellent.
