The front sight didnt come thet way dopey. somebody cut the ears from it beacause they probably kept trying to sight thier target with one of the ears as the post. I bought a low numbered Inland GM that had the same thing done to it. also my stock was sanded down and varnished with a clear varnish, the handguard was shaved down flat and a rubber recoil pad added. Why the .30 carbine needs a rubber decellerator is beyond me. I fixed the front sight (they are a pain in the butt to replace) I have yet to replace the stock since my wife shoots it more than me and she likes the stock the way it is, I will probably someday get a paratrooper stock for it.
Back to yours.... It should be worth in the range of 3 to 400 bucks as it is. If I were you, I would do my best to restore it to mil-spec and enjoy it. Auto ordinance has started making them again but they dont 'feel' the same as an original
