Frigidiare washer right before the new "Jet Action" agitator was introduced. Probably around 1963-64 model. A good machine. The one I had like this one was a roller matic machine, but this was also during the transfer from multimatic to roller matic mechanisms and I have seen machines with this same green and yellow console which were of the multimatic variety also. Good machines that washed, rinsed and spun out very well. Just tangled somewhat, when not loaded properly.
I have a similar transitional model of this washer sitting in my basement, but instead of a soak cycle, it has a gentle cycle on the lower part of the timer dial and it has the space capsule agitator. It is white.
