The top strap is marked "WILLIAM BISHOP. 170, NEW BOND STt LONDON". The right side of the frame is marked "ADAMS PATENT NO 41237", with the serial number repeated on the cylinder. Fixed sights, "445" marked on the trigger guard and loading lever, British proofs appear on the cylinder between the chambers at the rear and fitted with a checkered one piece grip.

Very fine. The cylinder retains 90% original blue finish thinning to a brown. The barrel and frame retain 80% original blue finish with the balance a smooth brown-gray patina. The trigger guard retains strong amounts of blue in the protected areas with the balance a smooth brown patina. There is some minor spotting. The hammer, grip tang and buttcap retain some flashes of original case colors, otherwise a smooth gray patina. The grip is excellent with some scattered minor nicks in the overall crisp checkering. Mechanically excellent.
