Early color articles in Chicago Tribune

[David Roper]

What's with the myopic insistence that the only set that existed at the time was the Model 5? The article makes direct reference to Zenith and GE sets. There were prototypes made by other manufacturers as well, likely most of which that existed at the time would have been pressed into service for that broadcast.

I hope you were not referring to my comment as "myopic", especially because my intent was the opposite... 750 sets (or anything near that) would be multiple times the number of Model 5s built, which was not more than 200, I thought. That implies hundreds of others maybe, depending on how far off the AP estimate was.

Compared to, say, 5000 CT-100s, 500 H840CK15s, and no more than 100 each of anything else (if that even) sold later, anything near 750 is a LOT of prototypes made available for public viewing.
