I believe this is a baritone bugle. It's about 24 inches long. It's engraved, Elkhorn, a div. of Getzen, Elkhorn, Wis. There's not much info online about this horn, so I believe that it is quite rare. It is well used and is missing a water key. It may be missing other parts. I'm certainly not an expert. Please see photos since they are part of the description. There is no case.
