Thank you, Everyone:

I hope I can recall accurately to reply to everyone's comments.

To paraphrase a CR Lister "not as elegant" - this would reflect the sense behind my comment that the GS is a "crude piece o' work" for Campag. GS has more unpolished nooks & crannies, profile more squared than rounded. Not bad looking at all but, lacking that Campag "bling". (May I say "bling" ? Is that Out of Timeline ? : ) ) Actually, the crank I have is in pretty nice condition.

Concerning chain ring bolts - I don't know the size. Crank I have does not appear to ever have been disassemble (chain ring bolt heads not rounded; no wear tracks indicating chain ring bolt heads had rotational contact against the ring). Apparently, two different chain ring bolts sizes are used. An inboard located hex. bolt & hex nut secures the large ring to the spider. Several mm's above that hex nut & hex. bolt, is a slightly smaller chain ring bolt that secures the small chain ring to the larger. Yes, a typical chain ring spacer is sandwhiched between the rings. This smaller chain ring bolt consists of a hex. bolt and a typical chain ring nut (slotted barrel). The larger chain ring hex. bolt & hex. nut measure11mm across flats and, the smaller chain ring bolt accepts a 10mm socket. Incidentally, the hex. bolts mate flat against the chain ring; that is: chain ring is not recessed to nest the hex. bolt heads. I do not know if the hex. nut for the larger chain ring bolt is a standard hex. nut or some type of special design "hex. head barrel" vis-a-vis standard chain ring nut. Yes, these thousand words could have been summed by a picture.

Thanks again.
