Kuhnl & Hoyer Orchestra Signature Bass Trombone for sale. Inline 'open flow' Meinlschmidt valves, Bb/F/Gb/D, 9.5" gold brass screw bell with yellow brass slide. Comes with K&H hand rest and Marcus Bonna screw bell case. Great playing trombone and in brand new condition, as its only been out of the case a few times. Long story, but I'm a tuba player that does some doubling from time to time, and this deserves to be used! Please email direct for pictures and price. Thanks!
