The Super Record rear derailleur on the 1st bike is very nice and better than the rest of the drivetrain. Any frame decals.
Those aluminum Geurciottis were real popular when I was at U of Central Florida in the mid80s. They were imported by a Melbourne (Fla) company called 10 Speed Drive. Nice bike and collectible but not real collectible.
The Gianella is interesting but I think the SR derailleur was added later as it is above the rest of the drivetrain and the geometry of the bike doesn't look like a racer to me.
