I'm fairly certain that the 75-150 was the only Oly zoom that ever was SC.
All other zooms were always MC. My 1984 edition of The OM System Lens
Handbook clearly says that the 75-150/4 was multicoated (quote: "Optical
construction: 15 elements in 11 groups, multi-coated" end quote). I believe
that the last of the 75-150's were multi-coated, but they seem to be fairly
rare.
Hope this clears things up a bit (yes, I'm being sarcastic),
