ltcnav,
Welcome to the Milsurps forum. And for a first post you have a very nice carbine to talk about.
You can look at back posts or threads on M1A1's from this site using the search feature. Already a few members are looking forward to seeing photo's. Some areas to get photo's have been mentioned. Others would be the right side of the stock, to see high or low wood. The bottom of the grip. And the leather piece and rivets.
Enjoy the forum and will be looking for your pictures.
Jim
