Manufactured directly after the 1917 military contract, these Commercial Model 1917s lack U.S. property markings. This example has a left over U.S. inspected barrel, which is chambered in very scarce .45 LC instead of the more common .45 ACP. The authors of the "Standard Catalog of Smith & Wesson" note only "several" examples of this model are known to exist in .45 LC. This is truly a rare S&W revolver which is missing from even the most advanced collections. The accompanying factory letter (copy) confirms the 5 1/2 inch barrel and .45 LC chambering. The letter also states the revolver was shipped to Fred G. Hammond of Canton, New York, on January 14, 1929. A lanyard ring is mounted on the butt, a common feature found on commercial examples. The revolver is wearing original checkered walnut grips. Matching serial numbers are on the butt, right grip panel (in pencil, faint) and barrel.
