I have a very old Frank Holton Sousaphone in BBb. It is missing neck and bits. I can make a part from existing stuff, but I would like it to be as close to original as possible.
Does anyone have any scans of old Holton catalogs they could post? Or pictures of an old Holton neck I could use.
This image from Conn-Selmer is close to what I have, but the image is too small to do me much good.

For further reference, what I have is the BBb version of this horn:

It is the 3 valve version of this horn, I think...

I will post pictures of this beast after I clean it up a bit. Wish me luck!
