It's the same one, 17JC55 chassis from 1977. That white 1974 Zenith 19" solid state b/w next to it was part of the same guy's collection which wound up on ebay.

I've never figured out which remote it uses. The Zenith manuals I have say SC600. But I've never found an SC600Z mechanical remote where the frequencies are right (and I've tried the ones with the orange, white, and blue on/off button). I've used a SC1000 electronic remote with it, and then it works like it should (with 5 separate frequencies: on/off, vol, ch up, ch down, mute - not 4 like the SC600 mechanical remotes). But because this tv doesn't have zoom, and all the SC1000 remotes have the zoom button that one isn't right either. I've been wondering if there isn't some mysterious 5-button electronic remote without the zoom which Zenith made specifically for this model.
