Manufactured from 1864 to 1869, this is a Fifth Model with longer and thinner grips and a barrel release spring not visible. The left side plate is marked with the 1864 patent date and "0" appears on the frame, grips, and barrel cluster.

Fine. The barrel cluster retains traces of original blue finish with the balance a smooth gray patina with some scattered mild pitting. The frame retains 70% original silver plating. The grips are excellent with some minor handling marks and retaining most of the varnish. Mechanically fine.
