I have a unit removed from an old Westinghouse Clothes dryer.  It is
a plastic box, about 10" by 8", containing metal bars and a rotary
pinned cylinder that lifts mallets to play the notes.  It has a small
motor, and plays the song "How Dry I Am, How Dry I am, How Dry I Am."
It was a signal that the drying cycle was over.

Anyone have interest in it?  I will sell it for $50.00 plus shipping
costs.
