That is beautiful. I also have a bike which should have a serial number but doesn't seem to, but mine (the red Urago on this site) also has a layer of crappily applied paint which the clues might be hiding under.
I love the top of the fork blades on this Cinelli, a glimmer of chrome with the Cinelli logo, then paint. Forza Italia...
This is one beautiful machine
A great build.
It obviously has a very interesting story buried beneath all the chrome and paint. Be very interested to hear what you dig up.
Thanks
Jamie
