You aren't kidding about the odd-ball tubes. The HV for the CRT goes through pin 6 on the CRT socket. I had one that worked quite well until one of the CRT leads broke even with the glass. I never could get a satisfactory repair.
Louis Mattar had a 1947 Cadillac on display at the San Diego Auto Museum. He had one of these TVs (beige and brown) mounted on the headliner for back seat passengers. Of course, he had to have the yoke rotated 180 degrees so the picture was orientated properly.

Unfortunately, it looks like the car may no longer be on exhibit. It certainly was a sight to behold.
