crtfool,
THANK YOU. "30-CTV1 4" Beam-Index color TV in the US, 1986" You got me going. If found, would be rarest of the rarest! :-)
Edit: Do you mean this one?

If the Sanyo prototype made it to market, I think it would have been designed much like the Sony Watchman flat TV's of that period. The prototype shown was much like this, with the gun inline and below the screen.
Here is a photo of the Sanyo beam index tube prototype:
