OK- I have sanded all of the bits and applied the first coats of varnish. I would say that the factory used a linseed oil but mine was so sun checked and cracked I need a finish that would harden up and hold much of the veneer lifted bits together. First coats are gloss which shows off the wood. Now I need to tone it all down to look hand oiled gunstock style like it came using a matt finish. I am not a wood person so some future collector will be cursing me.
Forgive the links-- somehow I cannot copy the correct bit on Imgur to get a photo to show up.
