Chambered in 10- or 12-gauge. Has 28", 30" or 32" barrel. It is a sidelock double trigger hammer gun, with case colored locks and breech. Barrels are browned Damacus-patterned. Checkered walnut stock is varnished or oil-finished. Colt's Hartford address stamped on barrel rib; Colt's name on lock. This has been regarded as one of the finest shotguns made in America, although Colt had difficulty competing with the less expensive European imports of the day. Production ceased after only 22,690 were manufactured between 1878 and 1889. NOTE: Add 300 percent for fully engraved model. Higher grades bring higher values.
