Dave Kerr a newer member over on Vacuumland who lives not too far from me is currently in Winnipeg Cda helping a friend on the restoration of a pneumatic Steinway Grand along with picking up some major vacuumabilia. He's posted a thread on the two of them restoring this remarkable piano. I'd always known about player pianos and how they sort of work but I've never seen anything as complicated as what these are. Well worth a look. I don't think, well I know, that I just don't have the patience for an undertaking like that. I could make the coffee though
