Currently the Electrolux-made Frigidaire TLs have a (very cheapened down) version of the Franklin mechanism which came into play sometime in the mid-80's (before that, WCI Frigidaires were simply Westinghouses with a 1-18 control panel). Slightly different than the older, fast-agitating Westinghouses and Franklins from the 60's, they have a longer and slower agitation stroke/index. Some still had a recirculating bed-of-nails filter and spin-drained, but the current Frigiluxes have a separate electric drain pump and neutral drain. I don't think the spin was as fast as it was, either.
Anytime you see an angel-wing agitator, bed-of-nails lint filter, and on later machines, a plastic tub, it's one of these. Their portable washer seemed to be VERY popular, as some of the brandnames it was produced under include the White-Westinghouse, Gibson, Kelvinator, GE, Hamilton, and Montgomery Ward names if not more. The 24" WCI Frigidaire Skinny-Minis also used this mechanism as well.
When we were in the Cayman Islands last summer, we had one in our condominium. Very fun to play with and watch, with the recirculating filter and angel-wing agitator, but the tub was way too small and the dryer was way too slow!!! I washed many loads during that week! Here's one of them...
