I won this cool old Colnago on eBay in September 2007. According to the seller, it's a 1972 Super Extra. It is definitely a 72 or 73 at the latest, but I've never heard of an Extra model, and none of the people I've asked have heard of it either (if any of you has ever heard of a Super Extra, please let me know).
I think it's an early Super Pantografata, or maybe a precursor to the Pantografata. Unlike the Pantografatas which were officially introduced in 1973, this bike doesn't have pantographed brake levers, and the chainring is also different - instead of being slotted and pantographed, it is drilled Merckx style.
UPDATE: It's not a Super-Pantografata. Unfortunately it's just a lowly and plain 72 Super ;)
