Hi folks!

I could use some help in identifying what year/make my Bianchi is. It was given to me years ago but I don’t have much info about it (I’ve tried searching for its serial number). Some info below.

S/N: BS353816
Decals: Piaggio, Bianchi, and Eduardo Bianchi (blue and gold)
Frame: white

I imagine it’s Japanese because most of its parts are?

Thanks in advance!
