Thanks to Bob, Aldo etc who responded to my enquiry.
It is a seventies frame...how early I dont know.
Any guesses most welcome.
It has a B in circle stamped at top of seat stays,
Two stripes and 'Bianchi' in the old typeface cast into the fork crown.
No brake cable or front changer brazings......
I realise the paint at the time may have been one of the more green celeste
colours, but I prefer the more sky blue shade...
If anyone can hold a pantone chart against their prized steed and e- mail the colour
reference, I'll be in business!
