I bought this M1A1 a few years back. It came out of an armory in Italy at the end of WWII and sat in a closet for many years. It was still packed with cosmoline when I got it. Inland manufacture with an Inland 6-44 dated barrel. From what I've been able to research, the receiver is from 44 also. It has the later style adjustable rear sight (properly staked) , push button safety, modified mag release, and blued round bolt. Every part and all the wood is Inland marked. As far as I can tell, it's only been proof tested.
