I, too, have a Stuyvesant player (65/88-note) and would love to know
more about it.  I am not sure of the model (or the serial number, as
it is buried in my garage), but mine has an interesting fallboard cover
that is separate from the fallboard.  The cover is hinged above the
keys, and hinges down on top of the keys reveling the player controls.

Being a combination 65/88, I imagine it would be earlier than a similar
piano having only an 88-note tracker bar.  I got the piano years ago
with the hope of restoring it (being a unique instrument), but that
will probably not happen.  Since mine is for sale, knowing more about
it may help with the sale.

Thanks, Richard Ingram
