The Colt Single Action Army in .44-40 was named the "Frontier Six Shooter", after J.P. Moore's Sons ordered some in 1878. Single actions in .44-40 were particularly desirable in the West because they could use the same ammunition as the popular Winchester Model 1873 rifles and carbines. The accompanying factory letter states the revolver was shipped to Pacific Hardware & Steel Co. of San Francisco, California, on November 13, 1912 with a 4 3/4 inch barrel in .44-40 caliber, blue finish, and type of stocks not listed. The barrel is stamped with the two-line Hartford address on top and "COLT FRONTIER SIX SHOOTER 44-40" on the left side. The left side of the frame has the two line, three patent dates marking followed by a Rampant Colt. The matching serial number is marked on the bottom of the frame, trigger guard, and backstrap. Matching assembly number "144" appears on the loading gate and back of frame.

Very fine, retaining 85% original blue finish with thinning to brown on the balance. The hammer and frame retain 75% original case colors. The correct pattern replacement grips are also very fine with overall crisp checkering. Mechanically excellent.
