Canfield notes that the World War II 97s left the factory with varnished stocks, and inspector cartouches. The absence of such markings suggests that the stock must be a replacement. Additionally, the buttplates of World War II Model 97 shotguns were plastic, indicating the buttplate on this is at best a replacement.
