These are 1970 500 series models, one from each of the two groups of 500 models offered that year. Both 500 series groups from 1970 looked very much the same, but were distinguishable by color differences on the escutcheon where the cycles are laid out, and more noticeably on the dial skirt. The washer, which has the chrome skirt is of the more full featured group, which I believe may have had a soak cycle, and a self cleaning filter. The dryer, which has the white skirt, is of the standard group. The washer match to this did not have a soak cycle, and it had a manual clean recirculating filter. These were very popular models in their day. I hope they find a good home.
Have a good one,
