Butt plate off and polished, found original serial number under all that and it cleaned up well enough to keep. Some deep pitting here and there but I can live with it. Rear sling swivel off also so only the receiver screw holding me up now. Butt is rotted about two inches down from the top Not sure how far forward it goes, maybe an inch and a half. There is also a quarter inch deep area that continues down the side which is where the cracking is seen in the above photos. I'm going to let the screw sit overnight and work at it again tomorrow but suspecting I'm going to have to drill it out. Busted one screwdriver tip and bent three others.
