I'm not sure if Bianchi kept that into the 70's. Hope this helps.
I have owned two Bianchis: 1962 low-end Corsa, 2F51703 and 1981 mid-high Campione d'Italia, 1M9914. I thought the first digit was the year of production, and the letter was either the month (skipping I, "M" = December) or the fortnight (A-Z, skipping I and O).
