Produced from 1866 to the late 1880s. Top barrel flat has the one line address and top of the breechblock has the 1864 patent date, with the serial number on the left side of the frame under the grip. Fitted with checkered grips.

Very good. The barrel retains 40% original blue finish with the balance a smooth gray patina. The remaining metal surfaces have a mottled brown-gray patina. There is some scattered minor pitting. The butt has been ground, along with a series of minor dings. The grips are fine with some minor handling marks (mostly near the bottoms). Overall the checkering is crisp. Mechanically fine.
