Practically nobody had recording equipment back then. Consumer wire
recorders weren't available until after the war. EH Scott was recording
broadcasts from Australia onto disks back in the thirties, and he might have
done some of that during the war. I'll bet there weren't any blank disks
available to civilians during the war.

Indeed I seem to recall something about how various recordings were lost
during the war because they were recycled due to shortages. Unfortunately,
I can't remember where I might have read that, or even if I'm just imagining
it.
