Hi Andy,
The excellent condition of the CRT came as a pleasant surprise, in fact the pictures look good with only 10KV so let's imagine what it will like with the correct 14KV EHT.
The heater voltage measures 6.1V so it's slightly under run. The mains dropper resistor is open circuit in two of it's three sections. Roger demonstrated that this component can be repaired with the correct type of resistance wire.
