I so wish JCP had put their appliance offerings in their catalogs like Sears and Wards, we'd know so much more about them and the chronological progression. I have a scant bit of JCP service info, mostly for their solid tub HP clones from immediately before this POD set. By the agitator, this looks to be mid-70's as it the same as in my Lady Executive Hotpoint from 1974, the first of the GE rim-flo design for the Hotpoint brand.
The agitator is splashy and a tad more noisy than it's GE cousins, and to watch it, the rollover isn't super impressive but as we all know, rollover isn't necessarily indicative of better cleaning and I've had no complaints with it's ability.
