Your rifle has a lot going for it. If you can afford it get the Bruce Canfield or Duff books. There is also a small blue Duff book with serial/drawing number match ups from original rifles. When I get time I can look to see how yours matches up. I don't have the dates memorized, but you have very possibly the original barrel, stock, and maybe some other parts. Yours has WW2 Lock bar rear sights, but I'm not good enough yet to know if they are type 1, 2, or 3. Yours may have only gone through one light rebuild but it's impossible to say for sure. Like the post above someone could have started correcting it. The only major things I saw in a quick glance of the photos was a rebuild p on the stock and the modified op rod. Fortunately during rebuild they didn't sand the GAW off your stock. I'll take a closer look at my book when I get time to help. In the meantime a real expert might chime in.

Best,

Tom
