Westinghouse H840CK15

Interesting that first article talks about the RCA and Westinghouse having different sized screens, 14 and 12-1/2 inches respectively. Did these sets not both use the 15GP22 (or comparable prototype CRT)?

Just a confused mix of different manufacturers PR. Both had 12 1/2 inch pictures, but some press releases stated the over-all tube size. Where 14 came from (instead of 15) I have no idea.

I just measured the phosphored viewing area of my 15GP22 and it is approximately 11.1 x 8.2 inches, which is very similar to a 12 1/2" Admiral (10.75 x 8.5 inches) and a 12 1/2" RCA (11 x 8.5 inches) so I think that it is accurate to characterize the picture as similar to a 12-1/2 set.

The opening of the double d mask surrounding the 15GP22 is about 12.3 x 10.2 inches.

The glass front panel of the 15GP22 about 14.7 inches diameter and the largest diameter is 15.75 inches to the edge of the welded flange.
