There are cracks in the " doughnut" but not too bad, right now I think there is nothing to loose in covering the windings with corona dope.

at this point I tend NOT TO believe what the meter is telling me, as when I had this apart, I took the chance to check the 2 resistors under the HV rect base, the 3.3 ohm to the heater is OK, but the 1m going to the CRT anode lead checked wide open, VERY BAD, even with it like that, I was getting 5kv at the CRT.
So...
I have a new 6BG6G coming, gonna try and dope the FBT as best as I can, replace the 1m, put it all back and see what happens.
If the 1 meg anode lead resistor is open(really good chance) they can still arc some voltage across the deteriorated carbon. Why not disconnect the anode lead from the CRT and see if your high voltage comes up, and if not also check on the fly end of that resistor? And NO those Fly 1 style transformers are not unobtainium.
