I was into bikes during that era. Though I don't recognize the brand name of the bicycle, I do remember that Campagnolo equipment was top of line. There was no better. Reynolds 531 tubing was also tops for frames.
This is a top of the line bicycle from its era. Like dave's analogy, it's like buying a Chevelle 454 (or Cutlass 442 in my lingo) in excellent condition, even though many of today's cars can easily outperform the old muscle cars.
I'm guessing that bicycle originally sold for at least $400.
