There is an interesting item at eBay auction.  It is a Regina Mandolin
Orchestra.  It apparently is a coin operated piano that is mechanical.
I bet the rolls are rare --anybody know anything about them?

 [ The Regina Music Box Company (a subsidiary of Polyphon Musikwerke)
 [ was America's dominant firm in the disc music box field, and began
 [ selling coin-operated pianos shortly after 1900.
 [
 [ The "Regina Sublima Piano & Mandolin Orchestra" plays a five-tune
 [ roll, usually made of heavy manila paper, much like a key-type
 [ fairground organ.  The mandolin version featured reiterating key
 [ strikes, and produced music something like a mandolin.
