I am hoping to get a little help from forum members. Over the next days I'll be taking a look at a vintage Torpado road bike, aparently from the early to mid 80's, that the seller knows little about. I've attached a picture of it, which unfortunately isn't very detailed. The seller mentions it is equipped with Campy components that are original to the bike. Having looked at the specs for an early 80's Torpado catalogue, it appears they could be Campagnolo 980, Gran Sport, or Nuovo Record.

I am new to vintage Campy and Torpado's, so could anyone tell me how I can determine which grupo is on the bike once I view it? Even better, anyone have an idea from the photo as to what year this bike was built, what model it might be, or what to look for on the bike to determine its age and value? Thanks!
