I fear this won't be much help to Scott Jamieson, but it may point to
one of the instruments from that Seattle Center collection which he
mentions.

The National Carousel Association held its annual convention in the
Seattle area about three years ago, and some of us wandered into a
nearby shop at the harbor while killing time waiting for the ferry to
take us to the island where the local Indian village is.  Scott should,
I hope, know what area I am describing so vaguely from memory.

Just inside the entrance to that little gift or trinket shop on the
right-hand wall was a mechanical violin, most likely a Mills Violano
Virtuoso.  By the time we fished around for a quarter to play the
thing, we were called urgently to head for the ferry.  So sadly that's
all I can report.
