The bike you are referring to was probably one of the Magni bikes retailed by ICS (Italcicli Cycle System) of Zurich. They modified and prettified Campag Record equipment and mounted their handiwork on Gold plated and chrome plated Magni frames.
Magni was a Milan-based frame builder, this much was conformed to me last time I was in the Masi shop in Milan.
There was a Peppino Masi who was a famous mechanic to the Italian cycle team. I think he must have had some connection because I had a
Magni frame that was engraved PEP. Just sold but should still be viewable on Ebay Item no.7236192395
I don't know id there is a family connection with Fiorenzo....
