This Model 5 version of the Model 1855 was manufactured in 1863 and has the two-line New York barrel address, a fluted cylinder with patent marking on one of the flutes, "31 CAL" marked on the right side of the frame, and the barrel and cylinder are stamped with British "crown/V" and "crown/GP" proofs. Unique "L" suffix after serial number. Given their sleek design which departs heavily from the usual Colt percussion revolvers along with their limited production and several production variations, these revolvers have long been popular with collectors.

Fine, retains 60% plus original blue finish with flaking and smooth brown patina on the balance. One of the screw heads is half absent on the left of the frame. The grip is also fine, with some scattered light surface crazing, some light handling marks, and defined edges. Mechanically excellent.
