The .44-40 WCF SAA has found a special place in the hearts of Peacemaker collectors. When introduced in 1877, the .44-40 WCF SAA was intended to be used injunction with the another legendary Western icon, the Winchester Model 1873 Rifle, which used the same cartridge. "The .44-40 WCF 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." The accompanying factory letter confirms the .44-40 caliber chambering and blue finish. The barrel length and type of stocks are not listed, a common indication of standard 7 1/2 inch barrel and walnut stocks, which this revolver exhibits. The letter also states the revolver was shipped to legendary Western gun shop J.P. Lower & Sons of Denver, Colorado, on February 8, 1879. This shipment was for 6 guns. J.P. Lower is credited for setting up the first firearms retailer west of the Mississippi River. Some of the most famous gun slingers of the day such as Buffalo Bill Cody and Kit Carson purchased firearms from his Denver store. The popularity of his shop led Lower to proclaim that "he had probably armed every Colorado Territory lawman, badman, Indian and gambler." The left side of the barrel has the highly desirable "COLT FRONTIER SIX SHOOTER" in an acid etched panel. In 1889 this highly desirable acid etched panel was replaced with a roll stamped marking. The barrel has the correct "44" caliber designation stamped in small font on the underside. The top of the barrel is stamped with the one-line Hartford address. The left side of the frame has the three-line patent dates marking. The left side of the trigger guard is stamped "44 CF." Matching full or partial serial numbers appear on the frame, trigger guard, back strap, cylinder, and barrel.
