John McClure asked [051215 MMDigest], "I have never seen any before;
are they rare and or desirable?"  And Robbie said, "Rare?  Yes.
Desireable?  Maybe.  How many functioning Duo-Art pianos exist that
can accommodate the huge spool?"

I bought a lot of them from Frank Adams for use as plain hand-played
pedal rolls.  Aeolian's 65/88-note pushup can accommodate them so they
were ideal for "shopping mall" music.  But several UK owners of Weber
Duo-Art grands, including Gerald Stonehill, seem to have no problem
with them.
