There is no question this Ainsworth has been on the raw frontier and shows it’s 149 years of age ! Serial No. 1250X was shipped to the Cavalry, maybe San Antonio Depot, on July 29, 1874. Since then, we can only guess the service it has endured. At that time about 322 were shipped, for issue to select cavalry units. 50 to a crate. I found it fascinating that of the approximate 12,000 Ainsworth revolvers produced, ONLY about 1,600 + or- are accounted for in collections! That means in any condition, not just all original. This Ainsworth , excluding the barrel length, is ALL original. It has ALL the parts it left Hartford with, no replacements. The barrel, in the day ( late 1800’s) was re-sighted and shortened to Six Inches, and shows appropriate matching wear. ALL Serial Numbers are matching, TG, BS, Frame, cylinder, and barrel, even faded in the one piece Walnut grip channel. Many features to the EARLY SAA’s are present: Italic Barrel Address, 1st style ejector housing, long knurled face hammer , the 1872 two line frame patent ,bulls eye ejector head and Inspector marks. Regarding Ainsworth Inspector markings: There are only two visible ones present, one on the trigger guard below serial number and one on the back strap behind trigger notch. This Ainsworth saw HARD use on the Frontier. Even the U.S. ( note: the early smaller size US ) is worn where the S is barely visible, while the U is definitively there. This Colt saw , as I said, unusual hard wear, even the Italic barrel address is hard worn, BUT visible.
