Manufactured from 1873 to 1878. The Schuyler Hartley Graham distributor diamond "SH" marking is stamped on the butt, and the barrel rib marking ends with "RUSSIAN MODEL." Matching serial numbers are on the butt and right grip panel. Matching assembly numbers are found on the grip frame, cylinder, barrel latch and barrel.

Excellent, retaining 95% original nickel finish with a mix of flaking and smooth gray patina on the balance (generally on and around the cylinder). Patterns of original case colors remain on the trigger guard, and 50% original case colors remain on the hammer. The revarnished grips are fine with some minor handling marks. Mechanically excellent. Provenance: Dr. Gerald Klaz collection.
