I don't think that Phil Wood says that pre-93 Campy
was JIS, just that they recommend a JIS Phil BB for those cranks. They're probably close enough, if you've got a set of cranks that's 15 years old, sockets worn a bit. And the older Campy spindle was in between ISO and JIS.
I think that the year Campy changed to ISO was 1994. But this thread has served one purpose: it appears likely that Sugino Mighty/75, SunTour Superbe and older Campy spindles were essentially the same in terms of the end-of-spindle. That leaves only the distance between bearing surfaces (thin or thick cups, etc.).
