I've just found 'BBC Stereo Test Disc' (Pye REC 355 Stereo, 1979).
Doesn't say too much about the frequency response/distortion/impedence
tests - on frequency test it says a measuring instrument with a flat
response is needed. The first side (IIRC) is Robert Dougal telling the
listener 'This is my voice from the left hand radiogram loudspeaking
device' and so on. I doubt it's calibrated or reliable but if you'd like
a scan of the sleeve notes, no problem.

No, that's OK. My question is because I'd like to obtain some new test LPs.
Ones with decent sweeps or sets of test tones at various frequencies,
levels, and distances from the center. Do Orthofon sell these? I assume
Shure abandoned doing so many years ago as they seem to have lost interest
in this area.

FWH I was quite dissapointed by the current HFN test LP. Seemed to me to be
a poor selection of tracks. Ended up using my 1975 'HFN75' disc for the
work I did recently. However I suppose the idea with the HFN disc is simply
for the user to check their playing force/bias and check the system is
tracking OK.

Slainte,
