Help identify DT Swiss wheels

Yeah, it turns out they are OEM, with the welded RR421 rims used on the (by now previous generation) 1400 series, but with 350 hubs instead of 240. I do wonder about the DICUT version of the 350, as those seem strange. I mean, I’ve seen plenty of 240 DICUT hubs and 350 SPLINE hubs, but no 350 DICUT hubs.
