CRs:
For what it's worth, Mavic did another variant of the MA2: the MA2 SBP. This rim has a hard silver anodized finish, it looks silver-gray. This rim appears to be the same as a MA40 except for the color of the anodizing.
I don't know when the MA2 SBPs were made, but I'd guess a 'middle' period because I've also got MA2s and MA40s with the same notation of MAVIC in a yellow rectangular label. The 'later' version MA2s and MA40s have MAVIC noted in a yellow oval.
(I'm calling the Mavic E2 period the 'early' period.)
Can anyone put a timeframe on the decal styles?
