There are some scattered spots of oxidation, some of the most noticeable are on the left side of the receiver at the rear. There are some scuffs that have thinned the finish and there is some thinning on the edges, most noticeable on the leading edges of the barrel and heatshield. The magazine tube has some areas of patina. There is some standard operational wear. There are a few streaks on the right side of the receiver where the finish is plum. The screwheads display tool marks with serviceable slots. The markings are clear. Overall, this shotgun rates in Very Good condition.

Mechanics: The action functions properly. This shotgun will slam-fire as designed. We have not fired this shotgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork & Accessories: Included is a Cody Firearms Museum records search which indicates that this gun’s serial number was applied February 23, 1918. A photocopy of the August 1945 American Rifleman magazine which has an advertisement for surplus shotguns, a copy of the relevant page from the Canfield book, and a green canvas sling are also included.

Our Assessment: After observing the Great War for the first three years, it became clear to the U.S. that serious close-range firepower was needed in trench warfare. The Model 1897 Trench grade was an evolution of this idea. The pre-existing Winchester Model 1897 was modified by adding a perforated steel heat shield over the barrel which protected the hand of the user from the barrel when it became over-heated, and an adapter with bayonet lug for affixing an M1917 bayonet. They were so effective and brutal in combat that the German high command once announced they would execute any US soldier captured with one in his possession. The 1897 Trench Gun would go on to see service in the second World War all the way through to the Gulf War.

In 1944 it became apparent to the U.S. that while there were available shotguns, many were not in acceptable condition. The guns had either been acquired under blanket procurement and were not the proper type, saw abnormally hard use and were not properly maintained, and others had just been in use for too long due to there not being replacements available. The military deemed that many of the weapons were in need of a major overhaul and initiated a factory service program with Ithaca, Remington, Savage, and Winchester which included trench and riot guns.

We think that this is one that was overhauled at the Winchester factory. Bruce Canfield notes in his book “Complete Guide to United States Military Combat Shotguns”, that “Some reblued M97 trench guns will evidence added punch marks on the receiver and barrel, and some collectors are of the opinion that these marks indicate factory reworked shotguns. While unproven, this theory seems logical”. It certainly does seem logical looking at this example. This WWI-era gun’s bluing is great, the Winchester proofs are crisp, and the gun has a later 4-row heat shield, such as would have been installed in a refurbish program to replace an otherwise unserviceable original 6-row. The gun appears to have seen some use since being refurbished, but retains a great bore and strong mechanics, in Very Good condition. This is a nice military 97 that will be tons of fun to shoot at the range and will be a nice addition to your collection. Please see our photos and good luck!
