This is a full double horn with A stop valve. It was made in 2000 in Germany, with serial number #20005. It is a detachable bell model with lacquer and 1 water key. It plays beautifully, but I no longer play professionally and it really deserves to be played regularly. A used Marcus Bonna flight case comes with the horn, as well as a stop mute and silent brass mute (mute only) if buyer wants them. I'm in center city Philadelphia and its available if you would like to stop in and play it. Sorry but I can't ship it just for playing. I have the benefit of traveling to most airports in the US (some Europe), so I may be able to hand deliver it. Please contact me with any questions. I have only played the horn on and off in the past few years, but it has been oiled/greased regularly. It will need new strings soon.
