I have a Winchester stock. Aside from the proof "P", it has the cartouche "AA" over "AS" where one would normally find a cartouche like "EmcF" or others. Anyone ever seen this before. I can't find it in the books.
I got one on a SG cmp rifle last year. Heavily sanded but clearly stamped AS over AA. Had paper wraping pieces stuck to it. Has deep red color. Had dried cosmo-linseed oil on it. Only came off with rubbing alchohol?!!
