Been looking online at a few of these Supraphon issues, as it was a little difficult to tell which were the stereo, and which the mono...
I had thought they were simply distinguished by the red label (stereo), and blue label (Mono), but further scrutiny shows that some blue label issues were stereo; You have to look for the two interlocking circles on the label which denote stereo, or the down pointing triangle which indicates mono.
The only other thing is that only some stereo issues have, not so much a prefix, but an "inter"-fix, with the letters: ST interposed between the prefix: SUA and the main cat number... so:
SUA ST 10495 (would be stereo)
SUA 10495 (Mono)
(But not all stereo cat numbers have this (So a bit confusing).
