Manufactured from 1876 to the 1880s, these large frame single action revolvers were also known as the "Army Revolver". This early model features an open top frame, scooped cylinder flutes, sliding loading gate and square butt with lanyard ring. The front sight is a blade integral to the barrel, and the rear sight is a "V" notch just ahead of the hammer on the frame. The left side of the barrel has the one-line Hopkins & Allen address marking, and the top of the barrel has the one-line Merwin Hulbert address/patent information. The revolver lacks a caliber marking. Most of the metal surfaces are adorned with factory engraved floral motifs. A stag scene inside a circular panel is engraved on the side plate. The serial number is stamped on the butt, and the assembly number "3189" appears on the grip frame, barrel lug and cylinder.

Fine, retaining 60% original nickel plating with a smooth gray patina on the balance. The engraving is crisp. The grips are good with moderately worn checkering. Mechanically excellent.
