That's a possibly interesting washer to me - with the model tag on the front cabinet, it pre-dates the 1983 models that were so heavily produced. If the console is original (they are easy to swap) this is a 1981 or 1982 machine, which were made in much lower volume due to the recession of the time.
The dryer is a 1972 60 series as James said - they were made well into 1974 maybe even 1975.
