Default Pitch Variable wooden propellers (WP)

I have saw a Continental radial engine with a 30 at list layers WP variable pitch!
Anybody has a graphic design of the attachment of the WP to the metal parts?
Thank you

It could be made in Micarta (http://en.wikipedia.org/wiki/Micarta) or Permali (http://www.permali.com/) and not in "true" wood.
I have a variable pitch propeller with this kind of blades :

It is from 1938 and was made for a Dewoitine 520 and blades are Permali. The root blade is slightly conical. I searched for a picture of the blade root, but don't find one. Not even sure we have ever dismantled one from the hub.
