I'm going to say '75 or '76. Probably the next model down from my mom's, which had rust colored cycle designations on the dial, and fake wood panels on either side of it. Hers had the "Quiet Pak" feature with the skinny belt, and Penta-Swirl agitator. I don't know if the advertised machine has either/neither/both, but it's probably still a fairly quiet runner. Nice machine, and the avocado works with the green accents on the panel.
