FWIW (and I know it's been done to death...), the MC 18/3.5 is the only lens
that clearly does not have the letter code (L.Zuiko*) on the rim (though it
does on the spec sheet at the back of the manual); the 24/2 _does_ have the
letter code (J) and no 'MC'; I can't make out the 28/2 or 35/2. (85/2 is
also F.Zuiko, no MC).
Also, the 1000/f11 is the only lens listed as using an apochromatic (front)
element.
Cheers
Andy
* The letter code is given in the manual (11/76), the lens is described
(both in the book proper and in the end spec-sheet) as having 11 elements,
but 'L' would suggest 12...

Interesting. Looks like the introduction date for the 8mm f/2.8, 18mm
f/3.5,
24mm f/2.0, 28mm f/2.0, 35mm f/3.5, 85mm f/2.0, 400mm f/6.3, 600mm f/6.5 and
1000mm f/11 was delayed versus what was listed for the system in the 1974
Olympus product literature. Maybe it took Olympus longer than expected to
perfect the multicoating mix needed for the elements in each of these
lenses.
I stand corrected that the speed wide angles were available at the time of
system introduction. If anyone determines the intro date on these lenses
(which were on 1978 price lists), please let me know. I have quite a few
additions and corrections to the multicoated lens list I cited.
