/Wurlitzer 125 factory conversion

I'm wondering if anyone has an Artizan A band organ (made for
Herschell) converted by Wurlitzer to play 125 rolls?  I have
just purchased one which was somewhat disassembled in the 1970s.
There are many parts but I'm not sure where they all go (especially
pneumatic parts).  An interior (from back) photograph or two would
would be helpful.  Thanks in advance.

Thanks, too, for all of the helpful emails regarding the Möller Artiste
player system.  Also, I ran across Mike Grant's name in the Archives for
Wurlitzer 125 rolls.  Have address and phone.  Is there a web site?
