Update: I’ve done a bit of research and I reckon this is a Sprint - I’ve changed the title accordingly. Still pretty sure it’s mid-seventies, it’s got the nice Bianchi stamped rear dropouts. I think later on they went to really cheap looking flat steel dropouts. Happy to be corrected/further educated though!
Got this to the stage where it’s rideable with a rear wheel rebuild and new chain.

Also fitted some lyotard rat trap pedals I’ve been saving. I’m loving the way this is looking and it rides really smooth too. This isn’t the final stage, I’ve sort of got it in my head to move the components and wheels off my Koga Miyata s/s bike to this and then redo the Koga with some period Shimano 600 parts and some nice old Mavic MA40 wheels I recently got.
