Selform?

IIRC, only Record parts had the Selform technology - the steel race was on a block of black polymer that allowed some give in the structure, reducing the fretting problem (often incorrectly referred to as brinneling). The BB cups look steel, but they have the same cut as Record, so if they are aluminum . . . The HS does look like Record, but if there is no black polymer under the bearing race, then not likely.

I've hunted around for awhile and found a number of photos of C-Record headsets for sale, and as far as I can tell they're the only ones with this distinctive shape and shoulder?
