My parents had a Kenmore of earlier vintage but similar looks. It was a cheaper model with only three buttons that had flat fronts, and no black on the panel, all woodgrain. Probably a '75 or '76. They decided to replace it in late 1990 when a door spring broke and the lower front panel had developed rust at the top, which had become unsightly.
What I remember most is how dramatically quiet it was compared to the uber BOL late 60's Wardgidaire portable toploader it replaced.
Thanks for posting. I haven't seen a good money shot of one of those Kenmores before and I had forgotten what the interior was like. A fine machine for a smart buyer and a real deal at $20.
