Hi all,  I'm writing this e-mail to help out a friend.  He is
rebuilding a previously rebuilt 1928 Kurtzmann Welte Licensee grand
piano.  At the back of the spoolbox is a "Transforming Lever" which
converts the Welte system to an 88-note player.  This particular
lever has four sections.  He has seen other Welte levers of this kind,
but they had a different number of sections.

Does anyone have a tubing diagram for this particular four section
unit?  Any assistance would be greatly appreciated.  Thanks so very
much!

Best wishes,

Mike Walter
