The acid test is the weight (the fact that yours has no chrome rules is out for a high end frame). A bianchi Specialissima in Columbus SL should weigh no more than 1925gr, frame only.
Your three tube tretubi del mondo will likely be 2100gr+.

Thanks again for the input, but what evidence do you have to back up your assumptions about the frame, as the 1981 del Mondo link you gave is clearly not "virtually identical" to mine? Certainly less identical than the 1976 Specialissima in the link I found, and the pictures I posted. On the other hand, though, I can't see any visual difference, framewise, between this 1977 Campione de Mondo CX:

and the 1976 Specialissima I linked to previously:
http://www.speedbicycles.ch/velo/265/bianchi_specialissima_1976.html
apart from the paint job.
They are both 70s though, not 80s.And why does not having chrome fork crowns or chain stays so categorically rule out this being a 'high end' frame? (and which models do you consider 'high end'?) What makes you so sure on this? There's no chrome showing on the seat stays or fork crowns on these:

http://www.speedbicycles.ch/velo/298/bianchi_super_specialissima_1976.htmlMine has chromed dropout faces (front and rear), if that helps...?
Weight-wise, I weighed it tonight, 2.925kg.
According to Velobase, the headset is 195g, the BB 290g, and lets say 10g for the seat bolt, so that's about 500g off.
Which leaves 2.425kg for frame and forks.
325g for the forks would be pretty lightweight, no?The 1925g is can be misleading too, depending what frame size it is for. They usually give weights for 54cm or 56cm. Where did you get this figure from ?

Thanks for the input. There's a 70s Rekord 748 on here:

The seat stay connections match, and on first look I thought the lugs did too, but on closer inspection the ones on mine are a bit longer and pointier I think.
I thought I found a site a couple of years back with 70s/80s Bianchi catalogues to download, but can't find it now.
What's the general model naming logic and hierachy from the 70s, between Rekord, Reparto Corse, Strada, Specialissima, Campione del Mondo, Classic, Super Leggera, etc...?
