The markings range from clear to worn, but legible. Overall, the shotgun is in Very Good condition as refurbished.

Box Paperwork and Accessories: Included is a 1917 dated Remington M1917 bayonet with scabbard.

Our Assessment: The Winchester Model 1912 was an improved version of John Moses Browning’s groundbreaking design, the Model 1897 pump action shotgun. While similar in most aspects to Browning’s design, several improvements were made by Winchester engineer Thomas Crossley Johnson. Johnson’s most notable improvement was to alter the action. While Browning had designed his m/1897 with an external hammer, Jonson modified the design with an internal hammer. The Model 1912 retained the distinct slam-fire action used on Browning’s original design and proved itself an outstanding firearm in numerous trials.

The Winchester Model 1912  did not just make an impact on the commercial market, the U.S. Government also took an interest in the innovative firearm. During WWI a militarized variant of its predecessor the Model 1897 was accepted for service (it is believed that the Model 1912 trench variant likely only saw limited use, if any, during WWI as Winchester prioritized the proven Model 1897 instead), remembered as the “Trench grade” variant, it had an attachment fixed to the barrel which features a bayonet lug and heatshield. The trench gun’s lacked notches on their barrels which allowed for the installation of an attachment which secured the magazine to the barrel, instead the bayonet lug secured the magazine on trench guns. Furthermore, authentic trench gun barrels were made without beads as the bayonet-lug/heat shield had a bead fixed to it. There was also a “riot grade” version of the Winchester m/1912 and m/1897 shotguns which lacked the bayonet lug and heat shield attachment, that was adopted for use in WWI.

The m/1897 trench guns were put to deadly use during WWI, their effectiveness prompted the German High Command to protest the use of shotguns in combat, the Germans claimed it was a violation of the 1907 Hague Convention on Land Warfare. The protest was likely prompted by the weapons effectiveness, rather than any actual moral scruples and was disregarded by the U.S. Government (this was the same German High Command who used poison gas in battle after all). Both the “riot” and “trench” grade shotguns continued to see use during the Interwar period and when WWII broke out the U.S. Government once again called upon Winchester to mass produce both riot and trench variations of not just the m/1897 but also the m/1912 for military service. They were used extensively in the Pacific Theater against the Japanese where hand to hand combat was all too common and to a lesser extent in Europe. Although its age was starting to show after WWII, the Models 1912  and 1897 would continue to see combat in both Korea and Vietnam. Both shotguns were expertly made and served the needs of American servicemen for nearly half a century.

This particular specimen is a Model 1912 which has correct features and markings for a Trench Gun. The buttstock is lacking an inspector or Ordnance cartouche, but is marked “AN” as found on guns refurbished by Anniston Army Depot. It is possible that the buttstock was replaced when the gun was refurbishment. Arsenal Refurbishment would also explain the parkerized finish, which is quite uniform and in-line with an arsenal-applied finish. The Model 1912 “Trench” variant is a very desirable collector piece, and this one even comes with an M1917 bayonet to attach to the lug. It will make a great addition and display in any WWII or Winchester collection. Please see our photos and good luck!
