Winchester model 63.....22LR
Cleaning is all I plan, for now. I got the forestock off, now I cannot get the screw / pin loose to remove the bolt.
Another stolen www photo. The pin, with the slot at the left unscrews. I injured my wrist the other day, and cannot break this loose. Might have to "borrow" my neighbor
Good page on the "guts"
