I've stumbled across this site with lots of old and new Campag gear for sale along with a 1974 Cinelli time trial bike (about 22-23 inches) and a Legnano show bike.
Normally, I keep all these interesting sites to myself but Campag stuff doesn't really appeal to me ;-)

I've never dealt with this lad before but he looks honest at least!
