Vintage MGM Studio Or Similar Prop Brass/Copper Bugle -No Markings READ

It looks like a 19th century cavalry bugle, but according to a pawnshop buddy of mine it's likely an MGM prop. He based that on the newer mouthpiece and the way the bugle was cut and put together. Apparently these props are quite valuable as well. It does not have any brand markings. Let me know if you'd like to see any other part of it in close up.
