Hi Bruce, yes this would be a reversing motor machine, No noisy power consuming solenoids, but the reliability was starting to go south for sure, LOL.

 WAS that they could run almost non-stop in laundromats for 10 years but in home use they did not last much longer, back in the mid 70s when I was working as a repair tech it was very rare to see a SQ ST washer from even the mid 60s still working.

These washers suffered from old 50s technology too many pot-metal parts that time quickly got the better of, including the inner tub base, the column that held and supported the agitator shaft, the very crappy water pumps that had non-exsistant water seals that if not greased regularly failed after a 1/2 dozen years. Add to a difficult machine to repair especially after water had been spraying everywhere over the mechanism and many users were ready for a better newer bigger washer that did not leave sand and grit behind and smell bad. So they bought a new washer like their neighbors new KM, WP or GE FF washer etc.
