To the best of my knowledge, these specific models were never sold in the US. If they were, the only reason I can think of is if there was some kind of production problem at Whirlpool, such as a strike, and Sears obtained them from Canada to have something to sell. The 5 program washer appears to be comparable in features to the US Lady Kenmore, and the 4 program seems similar to the 800 series. I don't particularly care for the control panels on the comparable US models of that time, either. These were immediately before the black panel models that were introduced in 1976, and I don't know if the Canadian models had the black panels like in the US, or not.
