So they milk it for as long as they can til production got too expensive

Exactly!

That Zenith b/w you have is very special though. Being a "C" line makes it a very scarce 1972 model which was the VERY LAST year Zenith built tube type b/w consoles. I'd certainly hang onto that one.

The Motorola is very nice too. It's about a '66 model. The "E" in the serial number means it was built at the Motorola plant in Elgin, IL. That too is a keeper! Very nice finds.
