Hi MMD'ers,  A couple of weeks ago I posted a call for help to see if
anyone could supply me with a missing part on my Aeolian 'Pianola',
namely the bass/treble expression control unit that has the foot pump
as an input and both sides of the pneumatic stack as outputs.

Unfortunately, no-one was able to supply me a unit at the time, so I'm
trying again to see if there is any one else who may be able to provide
me with ideally one of these units, or at least something that will
enable me to fabricate a similar unit (if possible).

Thanks,
Mike Green, CA
