Its been sitting in my utility room for the last 30 years or so. Had good emission last time I checked it.
The 12LP4 fits just about every late 40s to ~1951 12" TV. Dumont had a shorter neck tube and Zenith had a metal cone tube in that size, but a 12LP4 can be shoehorned in to those sets too. There's someone around Missouri or Kansas who was looking for a 12LP4.
Prior to the 16GP4 all US CRTs I'm aware of (20BP4, 16AP4, 12LP/KP/UP4 10BP/FP4 7DP4) used the same angle. Many chassis drove 2-3 of those types of different screen sizes unmodified. The 16GP4 is the oldest post war tube I know of that has an increased deflection angle to make the cabinet shallower.
