I like that NPM - like your coffee table, too! I have a friend that has an NPM close to yours - s/n 4,105xxx with a 10-43 Underwood barrel. His has a flip sight, push safety, type 1 barrel band, 2 rivet handguard, and an unmarked oval cut "high-wood" stock. It has an SG recoil plate, but I've never looked up to see if that might be a known transfer from Saginaw. It's been in his family for over 60 years. I started a thread on the forum about it a few years ago with some pictures. If you can't find it, PM me and I'll provide you a link. Does your stock have some modifications at the nose and at the front of the pistol grip? Thanks for showing it to us! - Bob
