I think I might be able to do us a great service if I could get my hands on even a rough copy.

German Parlophon and HMV also issued sets of frequency records, with tracks of fixed variable tones.

There were various issued here in the UK, some in sets. Examples I have in my collection are in the attached file, all UK except a couple as mentioned. Some of us are useful to us EMG/Expert enthusiasts.

If anyone knows a source for these discs I think I could get us some good info about frequency response and adding mass.
