Howdy Jesster,

Happy to read you have put it on the road.

Unable to give better information of this badge. Have never known a start or a stop date for it but it has been out of use for well over four decades. Yours is the latest example have seen. The forum has a number of Bianchi experts. They may be able to give a birth date for your machine from its serial.

Those five-piece steel hubs with the Bianchi stamping on the barrel are likely a good collectors item. They may have been produced by Fratelli Brivio of Brescia.

Enjoy your new arrival!
