This Es Altotrompet is made by "Bidl Brno". Alto trumpets are uset together with, or as replacement for Es alto horns not least in marching orchestras. They are also sometimes used as a solo instrument, depending on the repetoire, of course.
This was always well kept, but had a nervous player, I had to remove several deep pittings caused by perspiring hands.
