The '74-5 non-S model, with a detuned cam and an M front caliper, always struck me as a silly attempt at market differentiation. But I suppose that is just the automobile business, which probably is proof of the theory that luxury items can have a negative demand curve. Hard to believe the cost of production differential between those two models justified any price difference.
Since the A caliper was for Alfa, where did the M and S designations come from?

Right you are, just looked it up
last year for the front M was '75 on a 911
from '76 they all had A, except for the 930 and euro 2.7RS w/ 911/83 motor
no idea except that S was part on the early sport package, norm is Deutsche for standard so maybe idiomatic
