I recently spotted a Polyphon Concerto in an acquaintance's home
videotape and rather rashly offered to find information about it, but
my searches have been fruitless.

Can anybody tell me when and where these were made, how popular and
expensive they were, and where I can learn more about the company?
The owner of this extraordinary instrument has about 25 disks for it,
apparently about three feet in diameter!
