There is a crt on eBay that is from the 1930 s and the pinout is listed but why is there only 2 separate deflection plates but the other 2 seem to be tied to the 2nd anode at least that's what the pinout shows and it only has 8 pins on the end cap so it can't be used for an oscilloscope clock, I would need 10 for it to work.
