I have a complete pneumatic stack (note pneumatics, valve chest, push
rods, etc) and a few control handles and linkages from a Duo-Art from
a Steinway XR serial number 221330 that is suitable for parts.  This
is all that was left of the Duo-Art in this piano.  I removed it and
installed a PianoDisc system.  I will be glad to give it to someone if
they will pay the shipping.  I am located at Penfield, Illinois 61862.
