I guess I will embarrass myself by being the first to comment. I have been looking at a lot of references for several days, particularly since I am as interested in US Martial .22s as I am Winchesters. The stock color looks right to me, but after that I start asking myself questions. The trigger guard shape looks completely wrong for a Model 1904 or for any other low-end single shot, until we get to a Model 69. The pistol grip curve looks about right for a Model 69. I don’t know what to say about the rest of the stock.

I tried to enlarge the photo, but without any helpful results. At the time the Model 1904 was on the market, the military bought Single Shot Muskets by the thousands, plus Model 1890s in .22 Short, and Model 1903s in .22 Win Auto and 400 of the first 500 52s. Even high school rifle clubs were given Winders. Why would anyone want a smaller or lighter rifle, unless maybe for a grade-school level military academy?

I think we need a lot better photos and more details.
