This is a used Bb rotary trumpet of European origin. It's finished in lacquered nickel or nickel plate, and has seen evidence of some repairs. The finger buttons don't exactly align, but with some TLC they could. The receiver is too large for a standard Bb trumpet mouthpiece. You'll need a shim or maybe a contra-alto trumpet shank.
Includes a new Estrella trumpet soft case, slightly oversized but it works. Made by Adolfo Estrella, long time maker of Cronkhite cases.
