The infomation I was going to provide has already been provided!
I recently picked up a bike over in Italy, same frame and forks as this Cinelli, made under the name Garlatti, but branded as 'Cassia'. As these frames were sold to independent bike shops in Italy and branded as their own and then sold- bike boom era...
Mine doesn't have any of the chrome on the forks and lugs, and is currently built as a winter hack- abit of elbow grease and you'd have a nice looking Riviera there, don't see many of them about either!
