The revolver was manufactured in 1865 and has mostly standard commercial markings and features, including matching visible serial numbers. However, the left side of the trigger guard has an unusual "44 36 CAL" (factory error) marking and the "3" in the serial number on the trigger guard is double stamped. The grip has a raised relief caving of a spread wing eagle with a rattle snake in one claw and its beak and perched on a cactus and surrounded by oak and laurel leaves along with a banner inscribed "REPUBLICA MEXICANA" at the bottom. The design is different from many of the post-Civil War Mexican coat of arms themed carved grips found on Colt revolvers. Mexico was a key market for Colt firearms following the Civil War when government contracts in the U.S. were reduced.

Very fine with 70% plus original blue and 80% casehardened finish, patches of original silver plating, aged patinas on the silver and exposed brass, and general light scratches and marks. The markings remain crisp. All but one of the cylinder pins remain. The grip is very fine and has attractive natural grain and coloration, mild handling wear, mostly distinct carving, several minor age cracks, and minor edge wear. Mechanically excellent. This is a very fine '60 Army with a very attractive grip design. Provenance: The John Fox Collection.
