Well done and good instincts on pickup of the second bike!
It looks to me like the 2 bikes shared components from maybe 3 Campy groupsets. I believe a Croce D’Aune RD with C Record crank and shifters on the blue, a mix of older Record/Super Record on both bikes, Athena RD, brakes maybe?, and seat post.
