Dear MMDers,  I am looking for the small double (2-way) set of bellows
that resides under the air motor of some upright player pianos with an
Amphion stack.  The bellows activate the sliding reroll/play lever in
the spool box.

Does anyone have a set of these bellows in their junk box, or spare
parts that they are willing to sell?

Kind regards,
Geoff Ward
