ok so I scrubbed her down with #9 and a nylon brush. All the bug parts came off just fine and there was some hardish red stuff in the innards ... probably really old gun grease. You can see a few areas that have some bubbly little rust patches on them ... notably about the barrel and around the safety and that metal plate. I didn't notice any hard corrosion or wood rot anywhere. I'm not sure exactly how to get that rust off outside of some type of sanding or filing. I was wondering if soaking some of the bits in a little WD40 might help ... but I don't know what that might do to whatever parkerization is left on it. Anyway once cleaned a applied a thin layer of grease on the areas in a Brownell's video and some oil ... additionally I applied a tad on areas I could clearly see rubbing. I put her all back together, rubbed the wood down with a little Old English and a rag and called it a night. I ran a stripper clip full of snap caps through her and it seemed to be nice and smooth. The next test will be at the range with live rounds. I have some 150 gr Hornady American Whitetails and some 150 gr Federal American Eagles that say 'M1icon Garand' all over them lol.
