Manufactured in 1889. The Colt Single Action Army Flattop revolver is one of the most highly sought after models by Colt collectors. Not only are Colt Bisley Flattop Target Revolvers rare with only 976 manufactured, but this particular one is even more scarce in that it is chambered for the .38 S&W cartridge with only 39 produced. Adding to the rarity of this revolver is the fact that only a few had the London address on the barrel. The barrel is marked "COLT' S PT. F.A. MFG. CO. HARTFORD CT. U.S.A. DEPOT 14 PALL MALL LONDON" on top and lacks a caliber marking. The frame has the three-line patent dates marking on the left side, and the trigger guard is marked "38 CAL" on the left side. British proofs are stamped on the underside of the barrel and on the rear of the cylinder between each chamber. Matching serial numbers are on the frame, trigger guard, back strap, and cylinder ("490" on rear face). The front sight is an elevation adjustable, removable blade with the rear sight dovetailed into the top strap. All blue finish and fitted with checkered hard rubber Rampant Colt/American Eagle relief grips. No factory letter is available to verify caliber.

Fine, retaining 95% period refinished blue finish mixed with some minor thinning and some patches of pitting under the blue, most noticeable on the cylinder. The grips are very fine showing some minor handling marks and crisp checkering overall. Mechanically excellent.
