I am looking for the tubing chart for the player system in my 1923
Estey 5'2" baby grand piano, serial number 69498.  The piano was
advertised in the 1920s as the "Welte Built Welte-Mignon Reperforming
Piano (Original)" made by Welte-Mignon Corporation of New York City.

I have all the diagrams for the "Licensee" [Auto Pneumatic Action Co.]
system but none of them match my piano.  The suction is provided by
a turbine blower mounted in the piano.  Instead of a connecting rod
linkage as in the "Licensee" system, the expression pneumatic is
connected to the governor pneumatic control valve with a ladder chain.

This is my first reproducing piano than I am restoring.  I have
restored the stack and now I am going to restore the rest.  Any tips
or information that might be useful in restoring the Estey Welte
would be greatly appreciated.
