This is a very fine example of a rare late WWII Winchester parkerized Model 12 Trench shotgun as produced circa 1944/45. These were the last of the Winchester wartime trench shotgun that had the parkerized finish. It has the late style Winchester two line factory address, patent dates, Winchester legend and model markings all on the left side under the heat shield followed by "MODEL 12--GA.--2 3/4 CHAM./CYL." The barrel is fitted with the correct 4-hole perforated heat shield/hand guard with the bayonet lug mounted on the front end with the sling bale. The lower right side of the receiver is roll-marked with the large "U.S. and Ordnance bomb proof" directly below the ejection port. It has the late war oil finish walnut stock and ribbed pump handle. The left side of the stock is stamped with the boxed "GHD" cartouche over the cross-cannon Ordnance Corps final inspection proof. The stock is fitted with a Winchester checkered, black plastic buttplate with the Winchester logo in the center of the buttplate and the original Winchester lower sling swivel.

Extremely fine with 98% plus of the original WWII Winchester parkerized finish with edge and high spot wear overall mixed with some areas of dark brown patina/spotting on the heat shield and top of the receiver. Stock is fine as it has been lightly cleaned with a larger cracked and repaired area directly behind the receiver with a heavier scratch on the right side of the butt.. The stock retains clear sharp cartouches and proofs. The Length of pull is 13 3/4". Mechanically excellent.
