thick cup Italian, the "threading" in the center holes was called "rifled". The spindle is a post-'78 made for an Italian cup set (70) and for a road double (SS)...what's the length? That will determine if it's a Super record or a C-Record. The bearings are 11 1/4" balls from an earlier Nuovo Record, I think these will not be compatible with that spindle (and perhaps those cups) which I think should take 14 3/16" balls. Are the bolts magnetic?
