Consider the shapes of the leading and trailing edges of the counterweights.
Experiments with shape run quite a while ago showed that the rounded leading edge and tapered trailing edge had the least amount of drag. So, I would say the crank manufacturer knew EXACTLY which direction the crank would turn.
R. I bought a new K1 4.500 RB crank a few weeks ago, it has the same counterweight shape on the leading/trailing edges as described. This seems to be the conventional wisdom these days.
