When introduced in 1877, the .44-40 W.C.F. Single Action Army, or Frontier Six Shooter, was intended to be used in conjunction with another legendary western icon, the Winchester Model 1873 rifle, which came standard in the same chambering. "The .44-40 W.C.F. was added to the list of Colt calibers for use with the popular Winchester rifle of the same caliber," wrote Colt author David Brown. "This combination of a rifle and a six shooter using the same cartridge made it possible for their user to buy only one kind of ammunition, and he could carry 'fodder' for both guns in the same cartridge belt." Manufactured in 1884, this example has the standard one-line address on top of the barrel and "COLT FRONTIER SIX SHOOTER" in an acid etched panel on the left. The barrel is also marked "44" on the bottom. The left side of the frame is marked with the three-line patent dates. Matching serial numbers are visible on the frame, trigger guard, and back strap. The revolver has the desirable nickel plating and is fitted with a one piece walnut grip.
