Offered here is a documented example of a Mexico City shipped factory engraved Model 1877 "Thunderer" revolver. The included factory letter states the revolver was shipped to famed retailer Wexell & DeGress of Mexico City, Mexico, on September 23, 1885 with a factory engraving, 5 inch barrel in .41 caliber, nickel finish, and pearl grips with carved Mexican eagle motif. This was a six gun shipment. Although the revolver wears a set of Mexican eagle carved pearl grips, these grips are not original to the gun. The cylinder and ejector rod housing have a gold wash finish. The barrel, frame, and grip straps are plated in nickel. The Colt factory engraving consists mostly of floral scrolls on punch dot background with fan motifs on the recoil shield, loading gate, and behind the hammer, wavy lines on the top strap, rear of cylinder, and ejector housing, and star bursts on trigger guard bow and front of frame. The barrel has the two-line Hartford address stamped on top and the acid etched "COLT DA 41" panel on the left side. Matching serial numbers appear on the frame, trigger guard, and backstrap.

Fine as a South of the border survivor with great appeal, proving that not all art hangs on a wall. The revolver retains 60% untouched original nickel plating and 40% of the period retailer applied gold wash on the cylinder and ejector housing. The acid etched barrel panel is clear. The engraving is crisp. The fine grips show similar "working gun" character from spending a lifetime in the hand. Mechanically fine.
