Zenith porthole questions

[Sandy G]

I THINK I read this here-Commander Eugene F. McDonald, Jr., the head of Zenith, reportedly DIDN'T much like television-Mainly because his nemesis, Gen David Sarnoff, of RCA, had most of the patents. But McDonald also saw TV was gonna be too big of a market for Zenith to ignore. So he told his engineers to develop a TV-but NOT to bring it out til they got it RIGHT.. Maybe THAT would explain why now, even 60 yrs down the road, the Portholes are STILL giving good service to appreciative owners..

Here are some better pictures.
It is a G2438RZ Lincoln model. It has a Brightener on the CRT and the pictures are after a "clean" and then a rejuvenate and the emissions are in the middle of bad and good I think it would still produce a watchable picture in a dark room for testing until I could locate a valid sub or a replacement. My guess it that this set was retired due to the dim CRT. But the price is right and I think I am going to try and get it if I can find room!
