Excellent Mike, that's awesome! So, for a permanent solution, do you have a proper step up transformer and space for it? My grandson wants to know if you're going to replace the dial lamps with color LEDs?

From what I have read elsewhere those short metal tubes where called "stahl" or steel tubes, and were developed, and originally produced by Telefunken in 1938. The first time I saw some was in a war time set another collector had, they looked like oversized 6H6 tubes, and from what I can tell they carried on making them in Germany, and Poland well into the 1950s (or later), maybe some other Warsaw pact countries as well. Do they all have eight pin bases in that set? A really strange pinout, five on one side and three on the other, I would guess that the three pin side is for the tube heater plus the cathode, but since the base has a key why bother?
