It can be a challenge to locate spindles compatible with the 74mm shell. Campag offered everything at one time: track, road, triple. They even did them all for 3/16" ball ~1962.
The fact that chainset is FB makes me think more "'50's" than "'60's." FB seemed to cease the manufacture of chainsets and headsets prior to the cessation of manufacture of hubs.
Usually when one encounters a Cinelli wearing cottered steel cranks they are the Cinelli-Magistroni five pin model.
