Nice frame. I'd love to learn more about these. I have what I believe to me a mid-70's
Fiorelli/Coppi Tour de France model. That's my guess made from pictures of similar bikes with the same components. It was a mid/upper range model with a mix of Gipiemme and Campy Grand Sport components, Campy drops and I think 531 tubing. Serial number is a mostly illegible 4-digit number, no Avogarda.
