I have had for some time now, perhaps a year or two, an instrument that even the music shop owner wasn't sure what it was, but he sold it to me fairly cheap. It is bigger than, but similar shape to a trumpet, has a largish bell, chrome plated, and absolutely no markings as to who made it, nor any serial number. The only numbers are the usual valve position numbers-12&3. A low "C" sounds a concert pitch "G" below the normal cornet "B flat" therefore somewhere between "E flat" tenor horn and cornet in pitch. So therefore it is in "G" I assume. My cornet, a Bach, is above it, to give an idea of size. The valves are top sprung, with pip and groove type location. Any ideas any one?
