I have 45 plus years collecting and researching antique firearms. It is a delicate and difficult process in dealing with antique guns. First, any refinish or reblue or alteration severly reduces value and resalability. If this were mine I would obtain a good used action rod. There are many companies that specialize in supplying original parts. As far as the stock is concerned, this is a different animal altogether. There is virtually no original replacement stocks anywhere. Remanufactered stocks are alright but arent for me. I would find some very talented woodworker to remove the bolt through the stock and install a like colored walnut plugs in the holes. He should also be able to repair the chip in the top tang. I wouldnt let him refinish or alter any other part of the buttstock. Even when repaired it is still a repaired gun and though it improves the value some it still wont increase the value much. GREAT guns none the less. I hope the bore is clean and shootable.
