> Jerry and Ron, is there any paperwork about this at the site?
Mike- Ron Dethlefson has a chapter on those Ediphone training cylinders
made using the Blue Amberol materials in his book "Edison Blue Amberol
Recordings", 1912-1914, pp. 197-203.
I don't work with the paper archives here at Ediosn NHS, just sound
recordings and phonographs. Please contact our Archivist Lenny DeGraaf,
> Is the equipment still around somewhere?
No, there is no 1940s-1950s Ediphone Blue Amberol manufacturing equipment
at Edison NHS. You might try asking at the Henry Ford Museum.
