This early U.S. contract Cavalry Model Colt Single Action Army was manufactured in 1874 and sub-inspected by Orville W. Ainsworth. It is close to serial numbers 7918 and 7926 recorded on page 28 of "Colt Cavalry and Artillery Revolvers...a Continuing Study" by Kopec and Fenn as Ainsworth New York Militia revolvers. The revolver has matching serial numbers on the barrel (bright original blue remaining under ejector housing!), cylinder, frame, trigger guard, and back strap. The grip serial number begins with "4." The 7 1/2 inch barrel has a blade front sight, italic "+ COLT'S PT. F. A. MFG. Co. HARTFORD. CT. U.S.A.+" barrel address with die break in the "o," and "P" and "A" on the bottom ahead of the cylinder pin. The frame has the early two-line, two-date patent marking followed by "U. S." on the left and "272" on the loading gate. The trigger guard and back strap have Ainsworth's "A" mark ahead of the bow and behind the hammer respectively. The replacement grip has no visible cartouches.

Rating Definition:

Good. This revolver shows signs of a long service life and is typical of firearms that went to the American West. It received a period, possibly arsenal blue refinishing job at some point long ago and then saw subsequent use. Patches of this blue finish can be found in the protected areas such as in the loading cutout and under the ejector housing. The forward trigger guard screw hole exhibits numerous file and gouging marks. The balance displays mottled gray patina and patches of moderate pitting. The replacement grip is also good and shows moderate wear mainly at the edges. Mechanically fine.
