thanks for the correction i was going by what i saw happen in stations around LA in the late 40s when RCA tables were being replaced.
The last station that i remember had Gates CB14 tables with Gray 103lp transcription arms with the Gray passive equalizer.
My lateral World ets are all later i guess some have printed red vertical labels and sleeves with "LATERAL" stamped across them. And some are actually printed LATERAL...
