Since it's a used bike, you probably don't really know if that is the original wheel. Or if it is a Campagnolo cassette and free hub. Which might affect what you want to replace it with. Without know what they are on the current bike, you can't assume just because everything else is Campy that the wheel free hub and cassette are too. Unless you are able to make out the branding and part numbers on them still. If you post a picture of the free hub with out the cassette or the picture of the cassette when off the bike, we can tell by the pattern of the hole in the middle of the sprockets.

And why are you needing to replace the current wheels? Those pictured are not anything special. They aren't aero enough to be beneficial over any old rim with a flatter profile.
