Hi all!  I have rebuilt a 61-key (plays 85-note rolls) 'Tom Thumb'
expression piano and it works fine 'except' for the expression
regulator!

The original tubes were in pieces, of course, and I have not been able
to find the tubing diagram for it.  It is the expression regulator
illustrated in Reblitz's book: Player Piano, pg. 189, figure 7-58.

Does anyone have any suggestions or help in finding the proper tubing
for the expression regulator?  Thanks in advance
