In the early 70's, there were three primary SuperChampion tubular rims (or sewup as most people still called them then). The most common was Arc-en-Ciel, found on many PX10s and many other high end French bikes. This was the heaviest of the three, and the generally accepted weight was 330 gms, although I never weighed one. Even this was pretty light by today's standards.
The other two models, both lighter than Arc-en-Ciel, were the Medaille d'Or and the Record du Monde. I believe one was 280-290 gms, and the other was advertised as 260 gms. But I don't remember which is which. The lightest, whichever it was, might be OK for pursuit or kilo, but probably too light to suit most sprinters.

According to my old information, these rims weighed 330 grams (have one and it checks exactly); the truly light SC rim was the 'Medaille d'Or' which, at most, weighed 280 grams. Be careful with the MdOs (smooth style; smooth road; lower spoke tension) but I expect much more forgiving nature from the RdMs.......My own preference runs to Mavics from the same era, and although they were < in general> heavier, they were also more robust and provided longer and more trouble-free service.
By the way, the width of the SCs is slightly <20mm.
