Thanks
@BalkanExpress , I'm going to go for a 1972 Rekord Strada. The funky cottered crankset and centrepull brakes are a good indicator. Whilst the pedals and big silver dinnerplate chainguard look odd on a Bianchi, they were original equipment. I guess the former worked with platform shoes and the latter helped prevent your flares and loon pants fouling the chainrings!
Here's a link to a thread with good images of the same frame, showing the lugs and eyes, which also match the OP, and a scan from the 1973 catalogue below.
It's not a classic lightweight, but it's a good, solid Bianchi and definitely worthy of some love and attention!
