Manufactured in 1854, the second year of production for the 1851 London Navy. The single line "ADDRESS. COL: COLT. LONDON" marking with flanking arrows is on top of the barrel, with the London "crown/V" and "crown/GP" proofs on the left side ahead of the wedge, "COLT'S/ PATENT" on the frame, and the roll engraved Texas Navy scene on the cylinder. Equipped with the iron back strap and trigger guard, which were only found on London guns during this period, and smooth one piece walnut grips. Matching numbers on the lever, barrel, frame, cylinder and grip strap. Includes a relined, modern custom hardwood partitioned case containing reproduction Colt directions label affixed to the interior of the lid, "COLTS/PATENT" marked bullet mold, cleaning tools, nipple wrench, two spare nipples, Eley branded caps, oiler, bag flask, spare mainspring, two round balls, and six conical bullets.

Fine, retaining 40% plus original blue on the barrel and grip straps with a smooth grey and brown patina on the remainder. 60% of the case colors remain on the frame, hammer, and loading lever with a smooth grey patina on the remainder. The grips are very fine with dings and scratches as well as most of the original varnish. Mechanically fine. Case is very good with handling marks, as well as typical high edge wear on the relined interior.
