Gloger Sterling Silver Tenor Sax Neck. Ordered for a Selmer Series III and I tested it on one and it worked perfectly. I tried it with two Mark VI, a 92xxx and 112xxx.
The angle is identical to the Series III but the tenon on the neck is a bit small for them. This can be addressed by having a tech expand it or very simply with a small piece of tape placed on the tenon.
Will fit many Selmers or Selmer like horns, with some but not all requiring tenon adjustment. Neck is very clean, damage free and minimally used. The item "Gloger Sterling Silver Tenor Sax Neck for Selmer Mark VI ...
