I've refinished several antique furniture pieces where we used stains, linseed oil, tung oil, lacquer, or polyurethane, depending on the desired results. Now, I'm wondering what to use on my old Browning BAR rifle stocks(1970 mfg). It has a high gloss finish, resembling a high gloss polyurethane, without any amber or yellowing properties. What does Browning currently use or what did they use in the 1970's to protect the stock finish? Were their stocks stained and then sprayed, or just used naturally with a protective spray? Was it polyurethane, or something else to that effect without any ambering properties? I don't think that Tru-oil will give me the high gloss, uniform glass-like appearance that originally came on the stocks. If you have any experience with these particular stocks, please feel free to leave comments. Thanks.
