One of approximately 2,000 factory converted to cartridge c. 1873-1875. The barrel has the standard two-line address, and the two patent dates are marked on the left of the frame. Matching visible serial number "3141" on the barrel, frame, trigger guard, butt and cylinder, with "163" on the cylinder pin and loading gate, and an unnumbered wedge.

Very fine, retains 85% period retailer applied nickel finish with some light flaking around some of the edges and some areas of light freckling. The grip is fine, with some dents and handling marks, and some light edge wear. Mechanically excellent.
