Manufactured from 1874 to 1879. The upper left barrel flat has the Wesson & Harrington address and patent dates marking. The ejector rod, barrel and grips are numbered to the gun. Push type cylinder pin with spring button release and nicely figured bird head grips.

Fine. The barrel and cylinder retain 75% original blue finish and the frame retains heavy amounts of original blue in and around the protected areas with the overall balance a smooth brown-gray patina. The grips are fine showing some scattered minor handling marks and some high edge wear, with the left panel mostly absent of varnish whereas the right has most of its varnish. Mechanically fine.
