A DEG Dynasty 2 Mellophone/ Marching Trumpet/French Horn. I don't play this instrument so can not tell you much other than it's in overall good condition, The slides all move, the valves are springy and waterkey works. Could do with a proper clean, oil and polish. There are some minor dents and marks. The pictures form part of the description so please check them out before bidding. Comes with a case which is a little scruffy but strong and fit for purpose. It does not have a a mouth piece but they are available from John Packer for £11. I can also confirm it takes a standard trumpet style mouthpiece no problem. I understand from the internet that it plays in the key of G but as I don't play, I don't know.
