Thanks for your input, guys. I'd been watching this M1A1 for a while now and although it looks good to my inexperienced eye, it's hard not to wonder why it isn't bringing any interest because the reserve seems to be in the ball park if this carbine is indeed original and correct.
Because it is not original nor is it correct. The carbine looks to be correct, as does the stock, but the two did not leave Inland together as an assembled M1A1.
