Definitely late-70's, but one of the earlier black-panel machines. I wish they gave the actual model NUMBER as opposed to the model code so I could determine the date. One of the ways you can tell it's older than most is that the manual-clean lint filter is actually mounted to the tub ring and sits on top, instead of being integrated into the tub ring like on Jason's Frankenmore. This type is much more fun to watch, in my opinion, because they shoot the water straight out instead of downward.
I hope someone grabs it; it will be a fun machine to play with. No collection is complete without at least one belt-drive Kenmore, and you know it's low-mileage when it has the original sticker on the top!
