I can see that there was considerable variation in the faceplate of the Porta Colors, but it is not clear to me how much these TVs vary on the inside. The specimen that I acquired lost the label on the back of it. Is there something to look for on the inside that is useful for identifying the model or chassis? Is the faceplate useful at all for identification? The faceplate looks similar, but not identical to the WM203HWD4. My specimen as round knobs for things like color and tint, versus the flat knobs that the WM203HWD4 uses.

GE produced that set in different variations for about ten years.
Yours looks like one of the earlier models. You have to remove the cover and look for the tube location diagram. The chassis numbers are something like HB, HC, HD and HE with possibly a suffix number.
There's a great deal of difference of the earlier to the later models.
See if you could furnish a picture of the inner view.
