From what I've been able to figure out, it's a May 1942 Springfield with a replacement barrel from October of 1944. Most of the internal parts are Springfield, though not original. Most are from late war time to post war. All of the parts however are in absolutely fantastic condition with a nice green park on them all. There are only two non-Springfield parts, the trigger housing which is a 43 or later Winchester and the gas cylinder lock screw which is HRA stamped (looks brand new). The stock is also a replacement and has the National Defense Eagle stamped on it. It has a few knicks here and there but overall is in good shape. The muzzle gauges 1+ and the throat 2+.
So for my first rifle from the CMP, I certainly can't complain. I wanted a wartime Springfield and that's exactly what I got. Took it to the range this weekend to try out and it did pretty good. First shot was about 1/4" low from the bullseye at 50 yards. Good way to start. Here's some photos for you guy's to look at.
Right side of the rifle. I like the wood grain on this side much more than the left.

Not that I dislike the left side, just a bit less interesting to me.

6 digit Springfield. Serial dates to May of 1942. 30 years and a month older than me.

Left side again showing the National Defense Eagle stamp on the stock.



There were a couple layers of tape and paint on the bottom of the pistol grip. When they came off, the number 16 was there staring at me.

I believe the gas cylinder is a Springfield, though I may be incorrect.
