This Datsun was found in the yard of a Canadian Nissan dealership.
The model has been built from 1964 to 1967, changing its name from 410 with a minor facelift in 1965. As the difference between the 1964 and 1965 model is only recongizable by changed letters on the fender, which are missing on this car here, I can't tell whether this is a 410 or a 411. However, it was definitely built before 1966, as the grille changed in this year.
The SS-version was Datsun's "performance-saloon" with 65 hp compared to 45 to 60 hp in the normal models.
