Any thoughts on the steer tube? Does it need to be replaced? Or should I wait to make that decision until it strips when installing a Head Set?

I found an Identical (almost) Colnago fork from a Colnago super on ebay - I'll post pics on my blog...

I'm actaully getting some responses from there as well. One guy is telling me that since there was a magistroni BB on the bike and by the rust, that seems to have been original to the bike, that with the braze-ons for the pump, and the top tube cabling, plus the Magistroni, this would be from before the years that Campagnolo forced virtually all racers to use entire gruppos. So he was saying pre-1962. I guess campy decided that they wouldn't sponsor anyone that didn't use all campy components on their bike, so if they wanted free parts, the magistroni cranks, headsets, BB's etc would have to go...

What other marks, measurments or features can be used to identify? I know if I listed it for sale as a Cinelli, I would be proven wrong - so maybe lets find out what it is NOT...Any takers?
