Hey guys,
I bought a solid Birch MP44 stock from Dingo recently and it came with no finish whatsoever. I plan on using this stock so I want to apply a finish but I also want to get as close to original as possible. What would have originally been applied were it WWII? I know in the field they were using whatever was available at the time including motor oil but, by the book, what was supposed to have been put on there?
