Only around 2,000 "Pocket Navy" revolvers were 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. On this example the lower portion for the rammer remains open. The top barrel flat is marked "ADDRESS COL. SAML. COLT NEW-YORK U.S. AMERICA." The two-line Colt patent markings are on the left of the frame. "36 CAL" is on the left of the trigger guard, and "COLTS PATENT/No.163" is on the cylinder along with the stagecoach holdup scene. Matching serial numbers are also on the barrel, frame, wedge, trigger guard, and back strap. The arbor and loading gate are marked with the assembly number "117". It has the standard post front sight, hammer notch rear sight, and a smooth, one-piece walnut grip.

Excellent, retains 95% of the untouched original nickel finish with some scattered light flaking, mostly on the grip straps and edges of the trigger guard, showing the aged mellow brass beneath. The grip is very fine with some scattered minor dings and scratches. Mechanically excellent.
