Well, I may have found an answer. In Sutherland's, page 3-24, under Non-JIS Bottom Bracket Interchangeability, I found that a Sugino MW-68 spindle is not JIS (like Shimano UN72) but a Campy clone. Like I said before about the SunTour spindle -- it looks like a Campy to me; a spindle with a slightly smaller end; which at 2-degree taper, counts for a lot.
