I posed this question originally believing I was buying an
American-made electric Duo-Art, and was mildly curious what would be
involved in adding pedal exhausters to it.  I've seen foot pumps on
several European Duo-Arts and thought they were cool.  Seeing as
I started this thread I think I should jump back in with some updated
information about what I have.

The piano I got is actually a English made 6' Weber, and appears to
have been originally a pedal piano that someone has added a rotary pump
and Craftsman motor to.  It has a "C" cast into the plate at the rear
left of the piano, and has "Weber (Aeolean)" cast at the front of the
plate.  It has the "Pianola" label on the fallboard, shows remnants of
a pedal box on the lyre, and looks like the rotary pump was never made
to fit within the bracing under the piano.  It is a full Duo-Art as
best I can tell, with separate expression boxes feeding theme and
accompaniment.  The air motor to the right of the spool box has the 3
pneumatics arranged in a horizontal configuration, rather than vertical
as I've most often seen.  The control levers layout from left to right
in slots as follows:

*Left Slot marked "Pedals"
  2 levers for loud/soft pedals

*Next Slot marked "Duo-Art"
  2 separate levers (do these turn the theme/accompaniment on/off
  and/or control their levels?)

*Next Slot "Tempo"
  A long slot with a lever (even I know what it does)

*Last Slot on Right "Reroll, Play"
  Yeah, I know this one too.

There is no on/off switch, or overall volume controls that I can tell.
So I assume I'm correct that this was a foot-impelled piano once.

As such, does it make sense to restore it with pedals?  Of course I'd
want it to be electrified too, even if not original.  I think it would
be fun to be able to pedal it and add manual expression to 88-note
rolls.

Would it be too hard to pump, even in non-Duo-Art mode?  Would it be
too expensive to round up all the parts and make it work?  What other
considerations am I leaving out?

I'd also add that this is a very heavy, well-built piano.  I believe
the case is walnut.  It sounds pretty weak right now, but I'm sure it
will sing after a thorough restoration.
