I recently received my M1 Carbine in the mail from the CMP. I have yet to fire it, but I have cleaned it up a little bit. Did't take it fully apart because it doesn't really seem that dirty. Anyway, it is a Saginaw S G with serial range 32889** The bore has quite a bit of rifling left, and is really shiny. The barrel band is marked J.M.O. The sight of course is late feature and marked I.R. CO. I have two magazines, one marked IU and the other is IU in a circle. I don't know if I am reading this correctly but the magazine release button is marked WA and then M? If there are any other markings I can look for or anything, please let me know. Any help on determining the date and or any other cool facts are all greatly appreciated. I will get a picture up ASAP, but my camera is acting stupid.
