Thanks Bianchigirll !

What about this Bianchi, are the photos in the below album enough to narrow down which Piaggio era model it was?

From what I can gather, I think it was made in Japan, and came from a lower end line of models with high tensile steel? Suntour cyclone derailers, crank looks like it says 'sugino gs'
