I'm surprised you haven't either had one of these Westinghouse washers or worked on one in the past. Where I live, they were fairly common place. Before these top loading Westinghouse machines, I think that Westinghouse had contracted Easy to make some top loading solid tub machines with their name on them in the earlier '60's. I only saw one of those machines, so I am not sure of the origin of them. The original Westinghouse top loaders were a fairly heavy duty machine, back in the mid sixties. They had the swirl agitator that was black bakelite and were rated at 16 pounds for clothes capacity. They had the weigh to save lids, like the front loaders used to. The lids locked, like the later ones and there was a large solenoid that would kick in to tighten the drive belt for spinning. It would do sort of a neutral drain after washing and then the solenoid would kick in for it to spin. We had a neighbor that had one from about 1966 that lasted for 20 years without a repair. The matching dryer had been replaced during that time, but the washer was still going last that I knew, when she moved. They cheapened them through the years, like most things and they weren't as good a machine as they had once been. They were never that great at spinning the water out. They were on about a par of the older Kenmore/Whirlpool belt drive machines on that. They did wash pretty well though and the suspension system was quite good on the early machines especially. The later ones seemed to develop transmission oil leaks. We had a retail store chain here that sold them, so there were quite a few along with the Mongomery Wards models that were made of them too.
