The rear derailleur is not a match with the other campy stuff either. The RD is a 980 (or....i think there was a 990 model too or something? anyone). I could be wrong but I though that the shifters with campagnolo imbedded instead of raised were super record (but it also might have just been a change in the mid-80s which I would have to check on)... Headset looks like it could be nuovo hubs are GS. I think the FD is GS too but I am not that learned in Gran Sport yet though I have logged quite some hours studying record.
