Manufactured in the late 1850s to early 1860s, the U.S. government purchased about 21,000 of these revolvers by 1863 for use in the Civil War. The frame has the New York address on the left side and the 1856 patent date on the right side. Most of the components have single letter inspector marks. Matching numbers on the barrel lug, cylinder, hammer well, trigger guard, back strap, and hammer. The revolver is fitted with a one piece grip numbered to the gun on top and with a inspector's cartouche on each side.

Fine, retains 60% plus original blue finish and faint traces of original case colors with the balance having thinned to mostly a smooth grey patina. The grip is also fine with some minor dings and scratches, four punch marks in a line at the top on each side, and distinct cartouches. Mechanically excellent.
