The shop work in recently recieved a donated bike equipped with a set of pantographed Campy brakes

One of our volunteers identified them as originating from a Colnago. Any information including approximate value would be helpful. One appears to be correct, the other looks to have had its mounting bolt and hardware swapped out. I assume the pads are non-original as well.
Thanks in advance
