Couple of observations:
There seems to be a note missing in the Sams... the ohm table shows a tag for V1 and V2 pins 5&6, V3 pin 7, V4 pins 6&7. I suspect that these resistances should be measured to the 35Z5 cathode (pin8) and not to ground. With this assumption, your “wonky” restance readings look reasonable.
252 volts on V2 pin 7 can’t be correct or the 100 ohm cathode resistor would be smoking. I would double check the voltage and resistance values at that pin, and around that tube. Perhaps the problem is related to the area around V2.
