When I first saw the Popular Science article about the Sanyo color lollipop prototype, I was quite skeptical, thinking that the picture showed the common Sony 04JM monochrome lollipop CRT.
Looking more closely, it appears that the gun on the Sanyo is larger, the tube is thicker and the deflection angle may be less than the Sony (picture 2). I guess that I am more or less convinced that the tube in the article was unique.
