Glenn’s pictures show more clearly that it is indeed a pitman transmission machine. I could be wrong but it seems like someone said that the sliding water level switches were only on orbital machines. Maybe this one is a combination of two machines or maybe a mixture of parts from the factory.
Is it just me or does the washer lid look a different color compared to the top? Also the tub looks like the dark tub that was used in the small tubs. Maybe it's just really poor lighting on all.
