Interesting! I don't think that I have ever seen a picture of an early 15" set that did not have a CRT with an internal mask... Can someone perhaps post one?
A tube constructed in this manner (with the troublesome flanges designed out) might well be easier to fabricate today. I really like the funky looking internal mask, but having a tube that actually worked be great!
