Hello, my name is Bob Stratman.  I live in Batavia, Illinois.  I am a
hobbyist interested in pneumatic player pianos.  I own a totally restored
Cable Eupona.  I am currently working on, with professional help, a
Melville Clark Apollo expression grand.  The piano has a separate cabinet
that houses everything except the stacks.  It has two separate stacks:
one plays 88 notes and the other plays 54 notes.

If anyone has any information on this please let me know.  What I really
need is a tracker bar scale.  I would be very thankful for any help.
