Push feed Featherweight's are not that rare of a firearm. It's always a tough question to leave allow or refinish. The fact that you say the stock was re-done at some point makes the answer, to me, simple. As posted by others clean the barrel well and see if you can get it shooting reasonable hunting groups first. If it's shot out, and doubt it is, you should be able to find a factory barrel which will cut your costs of replacement. Then I'd turn it into a DIY project, do as much as you can yourself. Wouldn't get carried away, just a nice clean rifle with some history still showing.
