Can Anyone Tell Me About This?

I picked up this gum all machine and while I don't think it's a true antique, it doesn't appear to be a newer reproduction. The globe on it is wavy and has imperfections in it like it's blown glass instead of molded. And the bottom says made in the United States of America. When I opened it up I did notice that there is a plastic piece that turns where the gumball goes through. Any idea as to manufacturer and value?

Thanks for your help!
