Does anyone have a CONN 12m or 11m neck ( late series 1950+ ) they can measure for me ?

The dimensions I need are :

1. inside curve length tenon to tip
2. outside curve length tenon to tip
3. diameter of tube at curve
4. distance from mouthpiece tip to pip
5. inside diameter of pip
6. inside diameter of mouthpiece tip

any of these dimensions will be helpful.

Hopefully we will be able to make a few 12m necks for all the baritones that seem to be missing them ...

If anyone has a damaged 12m neck or parts of one that they want to donate to the cause or donate to get a manufactured neck in return at a low cost please send me a PM.

I do have 2 early Conn baritones with necks ( 1916 & 1926 ) that I can measure but I am not sure how these differ in dimensions

Thanks very much for all help

12m or 11m neck measurements needed. Maker needs these dimensions to complete the neck.

Total length, measured with a wire or cable inside against the curve

Minimum diameter INSIDE measured with calipers at the mouthpiece end

Maximum diameter, at the body tenon end

Distance from small end of neck to center of pip.

External dia of tenon,

length of tenon.
