Billy,
Welcome to VacuumLand!
I see your Tradition looks to be a 1979 model going by the smooth wheels alone, but what I do not see, however, is the lock on the headlight cap that would also indicate, when originally delivered, the top-mounted speed switch, that which has been removed from many machines produced during the summer 1979 period due to many people not being familiar with the way the newer speed switch worked (as opposed to the one at bottom that is mounted to the fan case).
