Bianchi Sprint 28?
I've come across this Bianchi on ebay and the seller seems to know very little but it's listed as a Sprint 28. I've exhausted all the resources I know of and I cannot find the corresponding model. I've asked the seller for more details but I'm not holding out for much...
Here are the pictures from the advert:
Can anyone shed any light as to what model this could be or even what era it's from. Unfortunately I have no more details to hand but the lady selling it is trying to find out more.
