I really don’t know much about this trumpet. It is labeled super tone band master made in Indiana. I was told it’s from the 1930s and it’s silver? It does not look silver to me at all. It is in poor condition. Needs polished. The valves are stuck. Not sure if you could repair this and actually use it or if it’s destined just to be a display. Just thought I’d see if anybody had any interest. Feel free to send an offer. Will mail it in the case, but the case also deserves to be thrown away. Serial Number 1788 (number listed on bottom side of middle valve) A very kind ebayer reached out and let me know that this trumpet is a stencil of the Elkhart Band Instrument Co made model 40B vintage circa 1929.
