Gun show carbines

[Singer B]

So that leads to a question for us novice collectors - what do you look for to determine if your carbine is original? I broke down my Underwood and completed a data sheet which revealed it has all of the correct parts it should have had when it left the factory. It needed a lot of love to bring it back to being a presentable and usable rifle. It looks original (patina, type 1, wear, etc.), the part diagram numbers say original, but how do I know it's original? This is a really interesting topic for me since I am currently looking at several other M1s for sale and I really wonder about my Underwood because it was a diamond in the rough when I got it and she became a true diamond when I finished her. After seeing some of the responses here, I now wonder how "original" she really is? Thanks!
