Welcome to Classic Rendezvous! There was a Vicini on ebay a few months ago. Dale Brown at Cycles de Oro shipped it for the seller, and took some pictures for the Classic Rendezvous website. No information, but nice pictures.
There is also a Vicini listed at Bicycle Trader Classifieds with a photo:
I really like these bikes, wish I could find a frameset in my size, 54-56 cm in orange & chrome.
