Manufactured in 1908, this is a rare and highly desirable example of a Single Action Army revolver documented as purchased by Wells Fargo & Co. to arm their express agency agents. On p. 105 of "Colt Peacemaker Collector Handbook and Guide" by Keith Cochran, it is noted that in the early 20th century Wells Fargo & Co. began arming all of their express agents and ordering large quantities of firearms directly from manufacturers instead of through local retailers. He notes that William Ashton, who was based in the company's New York office, was in charge of these orders. The included factory letter confirms the current configuration (grips not listed) as well as the "W.F. & Co." marking on the butt and shipment to W.M. Ashton of Wells Fargo & Co. in New York on 19 October 1908 in an order of 12 guns. The top of the barrel has the standard one-line address, and the caliber marking is on the left. The two-line patent date marking and circled Rampant Colt are on the left of the frame. The desirable "W.F. & Co." marking is visible on the butt. Matching serial numbers are visible on the frame, trigger guard, and back strap, and the assembly number "805" is marked inside the loading gate.
