My first Bianchi was a mustard-colored 1979 Super, all-Japanese but with quite upright geometry.
Too lively in fact with the curiosly-short, factory 8cm stem, so I sold it.

Years later, I came across the identical model in brown, laying in a heap with rusted-solid chain and wheels off the bike with obvious axle issues.
I bought it for $60, wanting to have another crack at this model.

Then along comes an Italian-built Nuovo Racing model in celeste, again in the same 58cm size as the others, but with a long original TTT stem on it.
Despite it having holes drilled into it's butted seat tube, and with it's fork crown rotated a bit to one side (and with fork blade damage crudely corrected using a bench vise), this quickly became my favorite, after installing a 5mm shorter stem and taking ten+ hours tearing through the bike.
I got the bike to ride perfectly straight, and it's proven to be a real crowd-pleaser among the club riders. And it rides fantastic, really supports the rider's effort in all road-riding situations.
