Well, thanks to all of your help I have uncovered the recoil plate and stock secret.
They are both Winchester.
The recoil plate "W" stamp was under a spot of rust on the top. Almost impossible to photograph but I think I got some of it in the left side pic. Right side pic shows approximate location.

The stock stamp was in the sling recess.
