By the mid sixties the 16" CRT was considered only for small screen viewing, a type of CRT to to be fitted in largish portable TVs. In terms of screen area it is slightly smaller than the mid fifties 17" CRT, actually when you look at those 17" rectangular tubes they do look really small nowadays.
The 19" CRT was introduced in early 1961 and was a squared up version of the awful looking 17" 110 degree tube.
The first 23" "square screen" CRT appeared in mid 1960 in the Pye V600A. The tube is the Sylvania 23SP4, I'm using the present tense because I have a working V600A and it is equipped with this tube, some later sets employed the Mullard AW59-90.
