Thank you, [MENTION=20548]JohnDThompson[/MENTION]! Could it be the record road/track hubs have been in production with unchanged shape for such a long time that it can be impossible to date them exactly?

The logo on mine has only the Campagnolo script with the globe:



Indeed, the locknuts don't seem to be original to the hub - they have no markings. Their edges ar also not coin-edged, they are just flat.

The cone nut has the inscription CAM 60 (or is it 09?)



And on the cone itself it says CAMP 9x26



The axle sais BREV CAMPAGNOLO:



Apart from this, I can't find any other inscription on the hub itself.

Thank you again!
