Tim,

Welcome. It is very nice to have you join the discussions here. The early Fox A grade is a fine gun! Hopefully, you will get years of pleasure from it.

Without seeing the gun up close, any answer is just a best guess. I see you are in PA. I can give you the name of someone local to me, who I trust, Dave Norin. http://www.davenoringunmaker.com/

I am sure others will be able to help with some one closer.

Pete
