A bit OT, but don't Schwing in his Mod 42 book and Riffle in his Mod 12 book refer to "Skeet Grade" for those two guns? I would think the marketing guys at Winchester would be somewhat consistent in their use of the term "grade." If one has a Mod 12 stamped "SKEET" on the bottom of the frame and choked WS2, with decent checkered wood, is that a "skeet grade" or is it a "skeet gun?" I think I know that there was some confusion about the Mod 101 skeets, with a designated "Skeet Grade" as well as field grades that were choked skeet/skeet and sometimes confused with the "Skeet Grade" guns (usually by sellers).
