@painter777 Thanks for all that info. The only book I have on carbines is "US M1icon Carbines Wartime Production". I'm in college so there isn't much "free" reading time.

There are no other marks on the flip sights. I took some pictures of the other things you asked about. I didn't know exactly what you meant about the groove on the front sights, so I hope the picture answers that. The barrel band seems to have 3 wield spots. There is another "TN" on the hand guard. I could not find any other stock markings but I saw a knot so I photographed it to see if you see something.
