Manufactured as part of a 25,000 gun U.S. contract during the Civil War and delivered to the Ordnance Department throughout 1864. "STARR'S PATENT JAN. 15, 1856." roll-stamped on the right of the frame, and "STARR.ARMS.Co.NEW.YORK." on the left side. Matching serial number marked on the front of the frame below the loading lever, cylinder, inside of the hammer well, on the left of both grip straps, and the top of the one-piece walnut grip. Ordnance sub-inspection marks are stamped on most components. Boxed script inspection cartouches stamped on both sides of the grip. "L.O." appears to be hand marked on the upper left of the grip.

Very good with 30% original blue finish mixed with mostly brown patina, traces of original case colors, mild pitting mainly on the top strap, and general mild overall wear. The grip is also very good and has smooth oiled finish, worn but visible cartouches, mild dings and scratches, and hammering marks on the butt. Mechanically fine.
