This is an absolutely gorgeous original EARLY WWII M97 Trench gun with no problems and no issues. Serial number is 925,551, putting production in late 1941 or early 1942. Original finish is about 90-95%. This trench gun has the 6-row heat shield that is typical of early WWII production (i.e. it is not Patent-marked like the WWI guns and is attached using larger rivet heads than the WWI guns). Left side of receiver is marked U.S., without the flaming bomb, as is typical of early WWII production. The barrel is dated 1940 and has the plugged front sight, as is typical of early WWII production trench guns. (NOTE: This is NOT a converted Riot gun--the barrel and magazine tube show no evidence of having had a magazine/barrel band on them. Rather, the barrel was originally intended for a riot gun but was used in trench gun production (do your own research).) An interesting feature of this trench gun is that the metal and wood finish are almost of commercial-production quality--another trait of the early production trench guns. The butt stock is correctly marked with the boxed WB and small ordnance wheel. The butt plate is ORIGINAL and fits perfectly--see pictures (this is very rare as the butt plates tended to break and need to be replaced on many of these guns. Note: Some of the pictures make the butt plate look brown--it is not brown, it is black.) Bore is nice and shiny with no defects. No import marks. This is a super-nice early-WWII Winchester M1897 Trench gun that is missing from most collections.
