anyone besides campy make a BB with rifled cups?

a-la nuovo/super record? I see a fair amount of vintage nominally campy compatible BBs from ofmega/galli/modolo/sugino...but never noticed any with the helical grooves in the cups.

Looks like the only ones. Shimano was the 1st i saw using rubber water seals tho.

Also Chorus, C Record, some others but all Campagnolo. Another small, sometimes overlooked, beneficial design quality that is pretty common on a lot of Campagnolo stuff.

QRs in the levers comes to mind.
