A similar machine was available for the 1980 season, which you'd see in the fall '79 catalog, but I would not call it exact. The "Heavy Duty Plus" campaign hadn't started yet, so the panel would be at least cosmetically a little different, and the machine itself would be of the original large capacity size, meaning most everything except the actual running gear was different (baseplate, tub, basket, suspension rods, etc. would all be different between the late 70s models and the 1981-1986 design). Feature-wise though, these machines are probably the same.
