1974 model, based on decal and first digit of serial number.
The fork crown looks exactly like that of my 1962 bottom-of-the-line Bianchi Corsa, and the downtube decal resembles that of my 1981 Bianchi, but it has under-BB cable routing and Bianchi decals on the seat tube, as well. Clear closeup photos of the various decals, particularly the one mentioning the tube pedigree, would be very helpful.
