The set shown in this thread is really impressive. Arvin engineer's must've thought, "We can build a set that is as good or better than the big guys."
They also built that model for Sears. It must've been their TOTL model that year. Those used either a 21AP4 or a glass 21ZP4.

Thanks for that info.
