For sale: a pump and motor removed from a Cable Expression piano.
I got these from a piano tuner who apparently replaced them with
a suction box.  Here's a photo of the pump, the motor is deeper in
my storage unit, but is in good condition and works.  (I'll dig it
out and send pictures to anyone interested.)

It's well-made (all Cable stuff is) and would provide great "optics"
in an orchestrion buildup (the outer bellows leaves move, rather than
the inner, and it seems to have a better connecting rod setup than on
an Ampico pump!), or be just a quieter vacuum source in an electrified
player piano (or be nice to have as a "spare" for one of these scarce
instruments.)  Best offer plus shipping.
