@Harb56 better photos would help. Show drive side details (component close-ups), and frame details (head badge, decals, engravings, stamps, lugs, drop-outs, etc.) with in focus well lit photos. It appears to be a "sports"/"recreational" "race" bike from the early to mid '70s; something akin to a Schwinn "Varsity" model bike. Details of components would help me to date it better. Some parts have date codes that, if original, can usually get to +/- 1 year of manufacture. The front derailleur and shift levers look like they might be Campagnolo Valentino group parts which were used c. late '60s through the '70s and even into the '80s.
My notes show it based out of Florence Italy. I show no connection to the Edoardo Bianchi brand. The brand may have been developed around the use of the readily recognized Bianchi name and its long heritage in the bike industry (there is another Bianchi brand also: Amelio Bianchi). They may have been involved with Beta Motorcycles.
Take care,
