It's been a while since I messed with the headset (and I don't remember what the measurements were), but when I replaced the old no-name headset that came with the bike, I had in my inventory a choice of an 80's-era Campy Record or the old headset off an early-90's Tiawanese Giant.
Alas, only the Giant headset fit. Looks like one more clue pointing toward Japanese origin.

I'm still wondering this too. And what model might it be? I'd have to guess that it's at least a Super Record level, but I'd like to know more conclusively.
It's clear it isn't a typical Torpado frame - we've all seen what those lugs (etc.) look like, but if not Torpado (or Miyata), what is it!?
