This example has a David F. Clark inspected "U.S." marked frame and a full nickel finish. Nickel plated Cavalry Models have taken center stage to a grand debate among Colt and U.S. military firearms collectors that continues on to today. Four basic theories for the existence of highly controversial nickel plated U.S. Cavalry Model Revolvers have developed over the decades and are the following: 1) issued to Indian Scouts and Police; 2) special order "officers" revolvers; 3) surplus State of Virginia Militia revolvers sold to and nickel plated by Colt or commercial retailers; and 4) U.S. Navy revolvers. For the history related to this ongoing debate see "A Study of Colt Single Action Army Revolver" pages 249-258. Clark's "DFC" initials appear on the barrel, frame, and cylinder. The "P" proof appears on the cylinder and barrel. The top of the barrel is marked with the one-line Colt address, and the left of the frame has the three-line patent markings followed by "U.S." The butt is inscribed with a large "C" in Old English font. The loading gate is stamped with the assembly number "337". Full and partial matching visible serial numbers located on the frame, trigger guard, back strap, barrel, and cylinder.

Very fine, retaining 80% untouched period retailer refinished nickel with high spot wear and some flaking. A back strap screw is absent. The undersized period grip is fine with typical age lines on the bottom and minor handling marks. Mechanically functions although needs work as it is missing the half cock notch.
