You could help us. Is there a company name on the device? A model number? Any markings at all?

Is it worth anything? Maybe. Depends upon the year and who created it and whether it works or not.

Also don't forget to search this on Google.

I bought it at an antique shop, I think it's from the fifties or sixties. Also is it worth anything?
