It's not quite as simple as that. The rings I have came off an alloy PowerTorque chainset, pretty sure it was Veloce (definitely not anything higher) and they had the hidden fifth bolt. Whether the bolt is offset I won't be able to confirm until I get back home tomorrow.
I have a 50t one available. Probably Veloce or similar not Chorus. It has the offset fifth bolt hole which I think was common to all 10 speed Campag compact chainsets.
Hardly used - £25 posted to UK mainland?
I haven't tried to find a colour match but I should do as it needs some touch ups.
I might also reach out to Dave Yates to see if mine was also built by him. It might explain them being the same colour.
Not really retro but worth a punt here before "you know where".
In good condition but there are a couple of scratches on the jockey cage and the top knuckle. There's also the usual discolouration of the back cage plate that the cheaper Campag mechs suffer from. The jockey wheel bolt Allen...

I have a couple of ES300 Octolink BBs lying around, I think one is 113mm and the other 118mm but I can check when I get home if they would be of any interest.
Pretty much all those negatives apply. You could probably also add not at all aerodynamic and given that the fast time trial courses back then were pan flat a pointless exercise in weight reduction.
A friend of mine back in polytechnic days decided to drillium his steel frame, I'll let you...
I guess the same principle applies regardless of whether it's Campag or Shimano. I was using an 8 speed chain which is just a bit wider than 10 speed so that's probably why the chain rub was happening. I have used an 11 speed chain on 10 speed chainrings and not had any issues.
Very nice! Looks similar to one I have, which EB dated to 1973 when I gave them the serial number. Mine is branded Favori and they had the name of the person who ordered it on file and that was the person I bought it from.
It was also a few years ago now so I'm surprised they couldn't help you...
