In regard to other uses for player pianos:  We used to have a
running joke when customers asked what the difference was between
and upright and a spinet player piano.  Our stock answer was,
"The uprights burn longer!"

It is sad to say that many of these old wonderful units are
seeing the bon fire or the fire place.  Perhaps that will make
all the rest worth more -- in about two or three lifetimes.
