Well, you have to consider the source of the Zenith claim of being the first to "sell" a NTSC color set....Zenith! They certainly weren't available to the public. Zenith was involved in color tv development for many years, and were involved in lawsuits with RCA at the time, and I think Cmdr. McDonald wanted to steal some of RCA's thunder with the claim of being the first to sell a color set, so they "sold" one to a local broadcaster! (Do you think it came with a service plan! ) I have heard this story from more than one source.

Unfortunately my Zenith is a LONG way from working. It is in fact missing the secondary chassis , which houses the power supply and the high voltage . I've never had the shrouding off of the CRT, so I don't know if it has a Rauland or RCA tube (I've been told that Zenith discretely used some RCA tubes because of manufacturing difficulties at Rauland), but the tube seems to be intact. My set is in storage, and I don't have any close-ups of the controls right now. Plus, there are supposed to be controls on the secondary chassis (missing on my set) that are accessed behind the flip-down speaker grill.
