Question about old Bianchi bicycle

I saw an old bicycle at local shop. There were texts "Bianchi" and "Gran Tourismo" at the frame. The
stem and straight handlebars did't look original so I wasn't sure if it had originally been hybrid
or touring bike. It had 3x6 speed derailleurs and cantilevel brakes. The frame was white with red or
pink dots and it was men's model. Top tube was horizontal, tube joints were lugged and the frame had
two bottle cage brace-ons. Drop outs were flat and cheap looking.

Id like to know the age of the bike and type of the tubes that were used in the frame. I'd also like
to know what level of components it does have. Any other info about this bike is also welcome.

My neighbors gave me an old Bianchi it has relatively light CRO-MO tubes and rather cheap
components.Buy the one you saw and at least you'll have a good frame.
