Greetings to Masi USA Owners- could anyone tell me when Mario Confente actually stopped building frames for Masi USA and then went on his own. Did he stop in 1975 or 1976? Were there any special features or colors of a Confente built Masi?Did he stop after a specific serial number? Thanks to all and keep spinning!Norm Hellman (owner of a champagne Masi GC bought from the Great One himself on Via Arona 19,Milano Italia!) Bronx, New York.
