I have cleaned her up a bit more and I think it is clearly worth chasing down the parts; Gun Parts Corp has them all for a little over $50 total. I think I'll try to find an original Remington marked floor plate and follower first as the rest of the parts are probably unmarked. Attached are pictures after a little cleaning. The 11 at the top of the butt I'm guessing is a rack number but I am wondering what the numbers on the bottom are?
