New to the forum. User andyscherer linked me to this thread from another forum as I was trying to date a Falcon Professional I purchased this past year, thanks Andy!
I've enjoyed reading through this entire thread and seeing all the photos. After a discussion on another other forum, I'm pretty sure my Falcon Professional is a '79 or '80, but I'm always open to other opinions. The foil headbadge (as I learned reading this thread) dates it later than '78. The Campy date stamps on the bike are from '79.
Anyway, thought you'd appreciate photos of another Falcon. Doesn't appear to have many miles on it, so I'm guessing it's the original build or close to it. I don't have enough posts to attach photos here, but hopefully this Google album link is OK to share.
