Looks like an ALAN produced frame judging by the lugs.

Did ALAN produce for Colnago anyone ?

Yes they did.

No, seller says in listing its a TVT bike, he's just trying to market it as a Colnago, which is bullshit because why would a superior Italian company who pioneered carbon frame manufacture with the aid of development agreements with Ferrari, ask a small french outfit to make frames for them? Doin the old 'slap a few Colnago stickers on and maybe no-one will ask' routine.

But Gregorio is right, this is a TVT frame and definitely not a Colnago (although some pro teams might have ridden a TVT frame badged as a Colnago as that was fairly common in the late 1980s/early 1990s when TVT were leading the way in carbon frames).
