Regarding the Aeolian Orchestrelle described by Bruce Grimes, not being
able to see or hear it, one can only venture a guess as to its value.
Condition is everything, of course.  As a wild guess I'd say maybe
$3000 to $5000, depending on the overall condition and how well it
plays.  A unit in bad shape or not playing is worth considerably less.
