Paraphrasing the book (cause I couldn't lift it) "In 1958 the first rectangular 17" color CRT, 70 degree was manufactured entirely of Japanese parts".
My question is: did they make a second CRT, was this a production CRT, etc.?
One thing for sure, I won't lose any sleep over it.

I wonder if this was the same tube used in the consumer 1958 model Westinghouse sets? I thought that was a 22" though. If they were different I wonder if our rectangular color CRT came out first?
