How does the bike ride? the video does not provide much help, other than showing the rusty bolts. I don't understand why you keep pointing to the Campi logo what we really want to know is wether there is a model name on the part and what it says. I can see on the rear derailleur that it says Campagnolo and then something else what is the other word? is that word or other words on other parts like the headset, shifter/brakelevers (brifters)?

are the rims Ambrosio? if so the wheel or wheels were rebuilt at one time, those rims were very out of fashion by the mid '90s when that bike was built.
