296 was the "don't quote me" number my LBS guy recalled from "back in the day" when he used to build this wheel all the time. I measured 603 ERD and 37.5 diameter, (he said 604) width 35.5 (center of flange to center) but it's easy to be off a mm. We're both in the same ballpark. So the fact that Mavic is off by 3mm is surprising to say the least.
