I don't know for sure (maybe Kaye-Halbert TV has other data that shows otherwise), but all of the first-year or so PortaColor sets I've seen had the controls arranged just as shown in that auction set, with the tuning knobs arranged up/down, and the five smaller controls arranged vertically near the right-hand edge of the front (and that little vertical line visually separating them from the rest of the front panel). GE switched to horizontally-aligned controls a year or two later on some models, but it seems like they kinda went back-and-forth a bit (and/or made some models in different control layouts in the same model year-- I think all of the clock-timer models have horizontally aligned controls, for example) until the "click-stop-UHF" tuners appeared in the mid 70's, when they pretty much stuck with the same control layout (horizontally aligned tuning knobs, with three of the five small controls just below, and the other two small controls hidden partially under the edge of the front panel).

As for when GE stopped using the PortaColor name, I'm not sure. It may have even been a gradual phase-out. It was definitely gone at the time of the click-stop-UHF tuners in '75, but I think it *may* have appeared on at least some models even as late as the previous model year. I'm not sure though.

I could be all wet on that, as it was pure memory and a conversation with Dr. Dan on the subject.
