Manufactured in 1877. The barrel has the two-line Colt Hartford address on top, the desirable "COLT NEW 41" etched panel on the left, and the serial number and patent date marking on the bottom. There are British proofs on the barrel and cylinder. The left of the frame is marked "41 CAL C." The rear face of the cylinder is numbered to the gun ("578") and the full serial number is on the left of the grip frame. Includes an oak presentation case with Colt London Agency label inside the lid and ten .41 CF cartridges. The included factory letter confirms the current configuration including the loading gate (barrel not listed) as well as shipment to Colt's London Agency on 22 November 1877 in a 30 gun shipment.

Fine, retains 50% plus of the original blue and case colors with the balance having thinned to mostly a grey-brown patina and some scattered small patches of very light surface pitting. The grips are very good with some scattered light handling marks throughout. Mechanically excellent. The case is also fine with some mild handling/storage wear.
