Just because you haven't seen anything does not make it untrue. Thee
was no "Photoshop" back in 1972.

I was one of the design engineers back in 1969 and 1970. The company was
sold (Should say given, he never paid for it) to a Jay Halliday in 1971. He
ran it into the ground and the IRS closed him up. He may have had a paper
thin model of a Rx, but never had the smarts or the ability to build one.
Subsequent to Halliday was Don Rohrs. He built the CX11 and later models.
There still was never a CX-5 or a receiver.
