I recently acquired an older tang safety M77. The stock is a little roughed up, but not destroyed. I want to refinish it and match the original finish and color as closely as possible. I bought a spare stock to practice on as well. I've already ordered the replacement grip caps and buttons too. I want it to look completely original. I've read multiple different articles and threads on it, and methods vary. Does anyone here have a tried and proven way to accomplish the factory look?
