Offer them $100.These are the ones that came with the houses in the neighborhood where I grew up.My parents turned them down(I wasn't around yet)because they already had a Bendix Economat w/ a rubber tub.A year after three tub replacents,They got a new Easy Rivera model two speed washer with the Spiral agitator.They also got a Sears Kenmore gas dryer.The washer took its last dump in October of '63 and we went o Sears and got the 1964 Lady Kenmore gas combination washer-dryer.
Most of our neighbors kept the westinghouse laundromat twins up to around 1975.The only ones I know that may still have theirs (the Schumchecks)also have the 1961 'Programed Computor'model with the rectangular window."flush,lift,turn,tumble 52 times a minute and free rinse,a spray of cool water as the wash water is draining before the first deep rinse to free clothes of lint and scum."
