Vintage Coronet With Case & Mouthpiece Unreadable Brand UNTESTED

The product is a vintage Coronet trumpet with a case and mouthpiece, but the brand is unrecognizable and the functionality is untested. This trumpet falls under the category of vintage brass instruments, specifically trumpets. It holds historical value for collectors or enthusiasts of vintage musical instruments. The Coronet brand is known for producing quality brass instruments, but the lack of brand recognition and untested status adds an element of mystery to this particular piece. Buttons go down and come back up nicely. Can't make out makers mark. Please see pictures as they are part of the description
