Manufactured in 1866. The top of the barrel is rolled stamped with the one-line New York barrel address flanked by dashes. There are a pair of British proofmarks on the barrel lug and there are "crown/V" and "crown/GP" proofs alternating between the cylinder chambers on the blank cylinder. "COLTS/PATENT" is stamped on the left side of the frame, "36 CAL" on the left side of the trigger guard. The full serial number with the letter "L" (indicating revolver was designated for sale in England) is stamped on the barrel, frame, trigger guard and back strap, with the wedge and loading lever unmarked. There is a faint English Enfield armory cartouche stamped on the left side of the smooth one-piece walnut grip.

Good. There is a smooth gray patina on the barrel and cylinder with the partially refinished cylinder having been cleaned and lightly machined during the period of use with at least one of the stop notches welded and re-cut with no approach re-cut. The loading lever and frame retain scattered traces of darkened case colors with the balance a smooth brown-gray patina. The cylinder has a couple small spots of pitting. There is some scattered mild pitting overall. The brass has an even aged patina. The slightly undersized grip is good with a few missing minor chips and some minor dings and scratches.
