Manufactured in 1874. O.W. Ainsworth's desirable "A" inspector mark is found on the barrel, trigger guard, back strap, and cylinder. A "P" proof is found on the barrel and cylinder. David F. Clark's sub inspection "DFC" stamp is on the bottom of the later production replacement grip. Both sides of the grip have script letter cartouches. The barrel has the one-line Hartford address. Matching serial numbers are on the frame, trigger guard, back strap, cylinder and barrel. The loading gate has the assembly number "540." Based on serial data complied by Kopec and Fenn, this revolver falls into the 6517-7527 serial number range of Cavalry Models issued to the 3rd and 7th Cavalries. This group of Cavalries was shipped from Springfield Armory in May 1874. Ainsworth physically inspected SAA revolvers recorded in the serial number range 200 through 14343. This was the first major block of U.S. Cavalry revolvers.

Good. Heavy amounts of original blue remain on and around the ejector rod housing, otherwise traces of original blue and case colors remain in the other sheltered areas with the balance a smooth brown-gray patina. The period removed patent date and "U.S." frame markings are no longer visible. The refinished replacement grip is good with a couple chips near the bottom, minor handling marks and faint cartouches. Mechanically excellent.
