These are very good necks, this one is in immaculate condition
It has Pete Thomas engraved on it. (I didn’t ask for that, they just did it without so much as a by your leave). I’m sure this can be removed humanely.
The tenon was opened up very slightly to fit my Grassi tenor, and it gave that horn a wonderful sound. The tenon now measures 27.9 mm (ish) but as with any neck you’d probably need to have the tenon either expanded or contracted a bit – which is entirely feasible and inexpensive as long as it it reasonable close to what you need.
It appears to be made of bronze with brasskeywork and tenon assembly. Lacquered.
