I have my heart set on a 1941 USMC replica. Anyway, I have the Unertl and have been looking for a donor rifle. I wanted one that was already drilled but then this one came my way. The rifle was literally filled with cosmolene-the GI stuff-not the CMP stuff. It has an 8-42 Springfield barrel with a mint bore. When I de-cosmo'd it I found the serial number on the bolt. The rifle is a mixmaster. The sloppy Hatcher hole is there as is that ugly gray park. I'm starting to think that I shouldn't drill and tap this one. If I knew for certain It was a Marine Corps rifle I probably won't. Any ideas? How about the stock markings?
