Yes these are Canadian models and many were sold in the 70's.
The interesting point with these Canadian models - these models were mainly had the Roto-swirl and straight vane agitators. There features were basic and great work horse. They were simple to use
The Dual Action Agitator was introduced in Canada at this time and they had a different type of control panel (looks more high end and extra programs). The higher end models also had the second rinse features too.
Generally, there were two design series (the POD design with the plastic modular control panel and basic features) and (the higher end models with dual action agitator, extra programs, fancier control panel, etc). Both types were great washers...
I miss the 70's and 80's Belt Drive Kenmores...such great machines!!
