Found this while I was searching on google a term "power twist tube" to see what else I have missed. and it turns out that not only there are companies to this day that still makes power twists tubes, yes, you heard me right THERE ARE STILL COMPANIES IN 2019 JUNE THAT STILL LISTS POWER TWIST TUBES IN THEIR LAMP CATALOGS!!!!! Also, I found this vintage pamphlet that promotes power twist with a double cathode mount in the picture. Neat.
