This is an update, and request for further info on our Recordo.

I received a note from John Tuttle, which was helpful, and Craig
Roothoff has helped a lot.  With his help it was discovered that this
piano has a H. C. Bay valve stack.  It has wooden valve stems, instead
of Bakelite.  Also it only plays 82 notes, leaving out the highest three
and lowest three notes, due to the width of the case.

If this jogs anyone's memory please respond; I'm still hopeful of
finding some kind of tube schematic.
