Originally manufactured as a percussion "Pocket Model of Navy Caliber" revolver, this example was one of approximately only 2,000 converted to the 4 1/2 inch octagon barrel .38 rimfire configuration c. 1873-1875. These revolvers had no ejector attached to the barrel and had their loading lever cutouts filled. The top barrel flat is marked "ADDRESS COL. SAML. COLT NEW-YORK U.S. AMERICA", "COLTS/PATENT" on the left of the frame, "36 CAL" on the left of the trigger guard, and "COLTS PATENT/No. 865" on the cylinder along with the stagecoach holdup scene.

Very fine, retains 60% original blue on the barrel, 25% on the cylinder, 75% vivid original case colors, and 50% original silver plating with the balance thinned to a mottled grey-brown patina and an attractive antique patina on the exposed brass. The grip is very fine with a few light dings, mainly on the butt, and retaining most of the original varnish. Mechanically excellent.
