Does anyone know the frequency of the diamond disc tuning record is? I recently picked one up, and would like to use it for adjusting the speed. If had to guess I'd say A-435, since that was the standard then. But I thought I read somewhere that Edison had all the instruments tuned to a diffent pitch at one point because it sounded better on the recordings.
