Looks like a late-80s/early 90s Super. The seatstay caps, BB shell and of course the braze-on FD tab all point in this direction. Later models - such as Grady's Elegant - ceased with the clover cutout in the BB shell. The cutout here is definitely the later version - the early version up to around 1980/81 had a pointed bottom to the clover's stem.

Another interesting note about the BB shells around this timeframe: there were a couple different versions with differing embellishments. Some had the clovers cast in (a la Grady's) the round portion of the shell, some had those same clovers cast into an aerodynamic addition to the forward part of the shell and some had the "Colnago" engraving as seen here. On the bottom, some had simply the clover cutout, some had "Brev. Colnago" as seen here.

Lots of variation even into the 90s - but I'm pretty confident this is right around the turn of the decade.

This one sure is a survivor if that's original paint - yellow is extremely hard to keep clean, not to mention trying to keep paint scrapes/chips hidden!

Nice
