Thanks for all the replies guys, found out the rear sight is not original so that kind of kills it for me. Also did some research based on what I read here and have discovered that I will never have an original WWII era paratrooper M1. Didn't know they went for as much as they seem to go for... Yikes... So sad!

Good thing though, I don't think I was prepared to drop that much on a rifle at the moment, hopefully in the spring I can find a regular M1 Carbine for around $1000 or so... We shall see!
