Parts pictures and cut-away pictures of the Fox action appear in all the catalogues, and there are several repros available from Cornell and others that are cheap.
I'm not a gunsmith. I'm a historical researcher. The last time I was inside a Fox was when my Super-Fox went to the bottom of American Lake in Colorado in 1970. If I have a gun problem it goes to a professional.
That said, I did try to provide one bit of info on the changes to the area where the tiptang joins the frame, but Cote' didn't use it. These pics are of guns from 1910 (wide radius), 1928 (small radius), and 1937 (nearly square).
