The Talking Machine Forum — For All Antique Phonographs & Recordings

Is there a resource for dating the manufacture date for Edison DD machines and also the recording dates for the disc's? Most info I'm finding suggests that this info was not recorded or made public?

Can anyone suggest good websites for other detailed information regarding the DD Machines and Records?

Thanks in advance for any suggestions or recommendations.

Bill

For the machines, I use Frow's "The Edison Disc Phonographs and the Diamond Discs." As for the discs, the thread with links to searchable spreadsheets is here: http://forum.talkingmachine.info/viewto ... t+dd#p6404
Another resource is "Edison Diamond Disc Re-Creations, Records & Artists 1910-1929" compiled by Raymond R. Wile and edited by Ron Dethlefson.
