In response to Katherine Bauer's request for information about
automated instrument museums, I would refer her to the Music House
Museum in Acme, Michigan, just north of Traverse City.  This public
museum is open for tours (although nearing the end of its season)
with a large collection of automated instruments and period displays.
Their web site is http://musichouse.org/ for more information about
the organization and its collections.
