In response to Mikey Mills' question about Knott's mechanical music
machines, I believe they were sold at auction when the park was sold
to Cedar Fair Amusement Parks, At least the ones in disrepair were.

I have one of those machines: a Nelson-Wiggen Style 3 with xylophone
that I've been told was in the Music Hall next to the Bottle House
at Knott's.  It and several others were purchased about twelve years
ago by Kim Bunker of Orange Coast Piano in Santa Ana, California.
