I picked up an 1892 in 38-40 today at a local shop, was someone's hunting gun - the wood was painted over (which appears to have preserved the wood) and had a healthy dose of brown patina. I carefully removed the screws for the stock and the crescent buttplate, and got the buttstock off and put stripper on it. It removed the paint (which stuck around pretty good, it took two hours of recoating and scrubbing to get it all off. I managed to keep the dark patina that comes with walnut aging for 120 years, and it had not been sanded previously. I tried to get the magazine tube out - the cross pin came out easy but never could get the screw for the magazine cap out. I plan on drilling it out and getting another screw - but there are two different screws listed - a long and a short. The long screw version extends out into a divot on the barrel. Obviously, I want to do as little damage as possible. Am I to assume that the originals like this use the long screw, and that is the reason I can't get the tube out? There is a little rust between the tube and barrel, as this gun was used for it's original purposes - I have a feeling it kept someone's freezer filled with deer during it's heyday. The bore is dang near perfect, and the rust on the exterior is super fine. I used a copper penny and Remoil and it looks very good now.
