Nice little bike. Yes, it's an Alan badged as a Guerciotti having Fanini sponsorship. May have been raced bitd for a pro/semi-pro team?
I note it has a couple cool little details: one, an Alan-pantographed seatpost and two, a pair of curved Campagnolo gear levers. Those are both uncommon items. Dura-Ace calipers - first generation? - are very nice bits as are the Campy Nuovo Record and Super Record front and rear derailleurs. Campy Super Record headset, too. Too bad the crank got replaced
I think if you spent 300 bux on that, you could look around for a retro crankset and be all set with a very nice vintage rig. IF it checks out well (as [MENTION=367427]xiaoman1[/MENTION] points out) and there are no cracks showing at any of the lugs, buy it
