Can you help to identify these frames, bikes or parts?

Over the years, I seem to have collected part of a vintage Campag groupset (maybe) and I am hoping you lot can tell me:

• what it is in terms of model name / year / etc
  
• what it's worth roughly on ebay
  
  

Here is what I have:

Close up of the front hub:

Close up of the rear hub:

Both mechs seem to be fine, but could do with a clean and regrease I guess. The front hub is smooth as butter and spins forever, but the rear could do with a service.
