It is a banjo mandolin? We have a Bacon & Day from 1929 that didn't cost too much to restore. They were very popular on the vaudeville stage in the USA in the early 1900's... petered out once the '30s swing jazz became the rage & talkies replaced live stage shows like burlesque & vaudeville. The old theaters installed screens & sound equipment that took up space & made more profit than the live shows.
