I have a couple of 3JP12 tubes with long persistence orange phosphor.
If you have access to the TCA data Cache shold by the tube collectors
association, the details of the P7 and P12 Phospour are in JEDEC release
3097 of 1961, with a mention that they in use long before the offical
release.
It looks like the P7 actually has a much longer persistence than the P12.
The P12 is described as being made of Zinc Magnesium Floride : Magnaise
The P7 is described as Zinc Sulphide : Silver and zinc cadmium sulphide
: Copper
