These are approximately 1985-1987. I purchased a pair of 1984's and they still had the woodgrain on the console. The next year (1985) they went with the chrome/aluminum and black consoles, like this pair.
I went to see them and they are in impeccable condition but as Lawrence said, they are "new." (too new for my collection) A nice lady was already there looking at them so I showed her how to use the mini-basket, lint filter and fabric softener dispenser and assured her these machines would last decades longer than the new crap they are churning out now! So, my search continues for the elusive GE Filter Flo set...
This is a late Eighties' set with the "Spotscrubber" feature and special mini-basket. They're TOL's and look like they were owned by a church. at 175, if they were in my neck of the woods, I'd have a hard time passing them up.
