Manufactured in 1855 at the Colt London factory. Features "-ADDRESS COL. COLT LONDON-" on top of the barrel, "COLTS/PATENT" on the frame, iron grip straps, and matching serial numbers on barrel, frame, trigger guard, back strap, cylinder, loading lever, wedge, and arbor pin. The revolver lacks the London proof and view marks commonly associated with Colt London factory Model 1851s. The period partitioned case contains a James Dixon & Sons Colt's Navy powder flask, cleaning rod, oiler, Eley's percussion cap tin, "L" shaped combination tool, and "COLT'S/PATENT" marked two cavity bullet mold.

Fine. The barrel retains 60% original blue finish. The hammer and frame retain 40% faded original case colors. Traces of original case colors remain on the loading lever. The cylinder and grip straps have a smooth brown-gray patina. The cylinder has some pitting and retains much of the scene. The grip is also fine with dings and scratches and slight chips at the toes with most of the original varnish remaining. Mechanically fine. The case is very good with numerous handling/storage marks, hairline crack on the lid and some wear and staining on the lining. The accessories are good to very good.
