I got it today and just uploaded a bunch of pictures. It's in better shape than the older photos made it look. I didn't see a brand inside but there's a chassis layout chart that says 19Q8. It has one of those horrid safety caps; seems corrective measures were never completed. It has a 25VEBP22 CRT with a date code of 7552, so chances are it was made early in 1976. I left the filaments powered up on normal voltage while I was out and it looks like this CRT may bounce back.
