I would say the bottom two might be from a fox model B. The top most definately one of the variations of a 311 or 411 made by savage/stevens. On second glance LC Smith is a good guess for the middle two. The bottom I see now is labeled fox B. That is probably right. The earlier "B"'s had checkering similar to those. If you don't want them, I'll send you the funds plus some to secure them for me!
