To preface my narrative, I didn't buy her. My dad purchased her from James River (maybe 2008?) when they were selling them, and I inherited it when he passed a few years ago. I ended up calling James River and was informed that they took really nice RCs with decent barrels to do the sniper conversion. I finally got around to taking the scope/mount off to see who made it about a week ago and it turns out to be a 1944 Gustloff Werke with what looks like a FN barrel on her. She's a real good shooter but feel free to rip her apart. 
Any input on what parts are forced match would also be cool.
