The included letter from Colt Industries lists the .38 caliber revolver in this set as shipped to Colt's London Agency on March 29, 1883, with 25 guns of the same type in blue finish. The latter is almost certainly an error given the revolver is in outstanding condition and always has been nickel plated. The .41 caliber revolver was also manufactured in 1883. Both revolvers have London proofmarks at the rear edges of the cylinders and underside of the barrels. They also have etched caliber and model markings on the left side of the barrels, the two-line Hartford address on top of the barrels, fixed half-moon blade front sights, top strap groove rear sights, caliber markings stamped below the cylinders on the left side of the frames, and checkered grips with "COLT" embossed on top. Gun A's grips have the matching serial number marked on the undersides, and gun B's grips are not numbered but fit perfectly and are almost certainly original to the gun. The revolvers come in a hardwood case fitted to the guns with red baize lining, a Colt London Agency label, oiler, cleaning rod, and key.
