Only a few thousand were manufactured from the late 1870s to 1880s. The revolver has an enclosed cylinder pin, scooped cylinder flutes, downward sliding loading gate, and bird's head butt. The barrel rib has the Hopkins & Allen two-line legend, and the frame has the two-line MH&Co. address and "38 CAL." Matching serial number appear on the grip frame, barrel, and cylinder.

Excellent, retaining 95% plus original nickel plating with some loss on the back strap and some scattered light flaking. The grips are also excellent with highly attractive fiery colors. Mechanically excellent.
