It is my understanding from a source in Italy that in the 1980's the Cinelli Supercorsa was made by an experienced Milanese framebuilder by the name of Mario Camilotto. The workmanship on these models is quite beautiful( I have one), perhaps even nicer than earlier models.I do not know why Signor Camilotto stopped building for Cinelli and why later frames were made by Losa, also in Milan.Norman (Nino) Hellman, Riverdale,New York.
