Manufactured in 1856 and almost certainly seen use during the Civil War. After the war, it was returned to Colt and converted for use with .38 centerfire ammunition for the U.S. Navy using the Richards-Mason system. The top of the barrel has the one-line New York City address, and the bottom has "R. W. M. [anchor]." markings of Commander Richard W. Meade of the U.S. Navy. An additional "U S N." mark is found on the butt. The frame has the two-line 1871 and 1872 patent marking and traces of the original "COLT/PATENT/US" marking. The matching full serial number is on the major parts aside from the cylinder which is numbered "4060" on the side and "12" and "61" on the rear face. The grip has "C. B." in large letters carved and filled in on the right side. "628" is marked on the loading gate.

Fair. The revolver has an overall dark artificial brown patina over patches of mild pitting and various minor marks. The refinished grip is fair as crudely repaired and has chips at the toe, some fill absent from the "C. B." marking, mild scratches, and a splice or repaired pieced wood with visible crack on the left heel. The action is mechanically fine, and the markings are mostly clear.
