The accompanying factory letter, which is addressed to noted Colt SAA historian and author John Kopec, states the revolver was shipped to the Colt's London Agency, London, England, on August 25, 1879. This was a 100 gun shipment. The barrel has the two-line Colt Hartford address on top and the desirable "COLT NEW 41" etched panel on the left. There are British proofs on the barrel and cylinder. The left of the frame is marked "41 CAL C." Both grip panels have the number "2500" in pencil on the back. The barrel and cylinder are numbered to the gun. The Colt London case has the Colt London paper label on the interior of the lid, has a brass inscription circular plaque with engraved initials on the exterior of the lid, and contains an empty cartridge block, an oiler, and cleaning rod. Provenance: John Kopec; Property of a Gentleman

Fine. The barrel retains 85% plus bright original polish blue finish and a crisp etched panel. 40% original blue finish remains on the cylinder with a smooth brown patina on the balance. The frame retains 30% original case colors. The period replacement grips are also fine with some high edge wear, some minor handling marks, and most of the original finish remaining. Mechanically excellent. The case is very good with absent lock escutcheon, worn lining, and minor handling/storage marks. The Colt London Agency label shows a handwritten note in pencil dated 1915.
