Can any Bianchi expert help? I am trying to establish what brakes the Bianchi Folgorissima came with? When the bike was renamed the Paris Roubaix they were the Universal Mod 50. I believe the Folgorissima also had Universal Mod 50, but these brakes did not come out until 1950. The Folgorissima was produced for one year spanning 1949/1950. Does that mean they had early release of the Mod 50 brakes or was the first bikes fitted with the Universal Mod 39?
My gut says the Folgorissima came initially with the Mod 39 and then then Mod 50 - but does anyone know?

Thanks in advance
