Wards = Hoffman/Cortron, Wells-Gardner, Admiral
In short, the 1960's Montgomery Ward color TVs were often Hoffman -
But there were many Montgomery Ward televisions made by Wells-Gardner too. Look for models beginning with WGEC or WG for Wells Gardner Electronics Corp.
That Wards Airline "5235" was likely the "WG5235" which would make it a Wells-Gardner set.
Wells-Gardner still operates in Chicago. Warwick, Wells-Gardner and Admiral were the three big OEMs in Chicago. Boy, with Zenith and Motorola too - Chicago seemed like THE place for television manufacturing.
I recall that after about 1970, Admiral chassis seemed to drift in their design style. I suspect they were using some Hoffman designs although i cannot prove that. (And why not? They owned them.) Rockwell International didn't come into play until about 1974.
In the 1970s, Admiral's designs became more refined under Rockwell International. I remember that Admiral and Wards TVs then became largely identical.
Admiral seemed to make some iffy decisions near the end. Their 1965-1970 picture-tube manufacturing plant opened when rectangular picture tubes were in short supply - ran into issues when the industry became over-supplied. Their water system was allegedly sabotaged and the tube quality dropped. I believe the phosphors wouldn't stick.
Admiral bought Hoffman/Cortron, a fading color-tv manufacturer in about 1970, just as the Japanese sets were taking hold.
Admiral supplied CARTRIVISION sets under Wards, Admiral and Emerson brands but that recording system went bust very quickly. This was about 1972. By 1974 Admiral was sunk.
Losers, losers, losers so it seemed.
I found Admiral an interesting company. I worked with quite of few ex-employees of that company. They seemed to do a good job of remaining marketable but went about it in somewhat screwy ways.
Did you know Admiral made their own microwave ovens in the 1970s? That seemed like a smart decision as Magic Chef continued to do so after purchasing Admiral in 1979. Wards used SHARP to make the microwaves through the 1970s and essentially through to the end.
Unrelated clarification: When CBS decided to enter the TV manufacturing business they bought AIR-KING, a small TV manufacturer. Air-King brand went away and was replaced by the CBS brand.
The tubes used in the sets were CBS-HYTRON
