Gloger Tenor Saxophone neck. Has some tarnish and light wear, but no damage whatsoever. 28mm diameter tenon. Fit Dorfler & Jorka or Keilwerth New King - and probably other German, Czech and Eastern European horns. Amazing tone on my New King tenor, but not what I’m after. Designed to help the higher end of the horn play in tune, as a lot of those horns play sharp up top. Postage anywhere at cost - or pickup in Brunswick west
