I recently obtained a "mystery disc" pressed by Columbia - laminated
shellac, just over 16", with a "Sound on Disc Division" label common
to discs Columbia manufactured in the early 30s. I've also run into a
couple of Victor transcriptions from the early 30s with blank labels
that have been difficult to get some concrete info about.
I've been curious if the ledgers for the transcription divisions of
Columbia and Victor or other labels have survived. Has anyone done
any discographical research in this area? I've seen some
discographies of Armed Forces radio transcriptions or Music Library
releases. The ledgers from Columbia and Victor and some other
companies, like Allied, would probably be of great interest to
researchers on film or radio history.
