I have the very same frame, found by the side of the road, and could find out very little about it. They were probably rebranded frames from an Italian manufacturer, although most of these frames seem to show up in Germany, so it is not clear if they were marketed in Italy or the U.S. I built mine up as a fixed gear, as it was missing the rear wheel. Mine has Shimano 600 (Ultegra) components rather than the Campy. I especially like the lugs, which are Bocama Competition 83

I am very happy with the bike. Hope you enjoy yours.
