Here is the Mafac catalogue c. 1976 from the same French catalogue site (which I find invaluable although apparently the chap who runs it is not well liked for "borrowing" material without credit)

I think the Competition levers were used with 2000s; they had the full hoods while the older Racer pattern were half hoods.

Anodized rims from 1974 onwards sounds very early to me. I thought these kicked in c. 1976 and later. Usually OEM fittings on machines like this was, if anything, less current.

Here is the 1974 range of Mavic rims:

The only anodised one was the Golden Monthlery but the Extra Legeres were certainly polished natural alloy... I have a pair. By 1976, yes there were the first SSC bleu and OR/AR models.

But yes.. just the differences in the Olympic models from 1974 and 1975 are enough to give one pause!
