I tested it as mentioned, the power supply I used for testing it had a constant current function and I took the supply up slowly to 40mA (the max it would supply) at this current it was putting 460 volts into the coil, which I sustained for around 8 minutes.
Fingers crossed it should still work in the speaker, though for how long nobody knows.
This is how to make a join in the wire, whilst winding, this one was done in 1930. I wonder if it was an accidental break or a change of reel.

Hi Mike.
At 11k it must go between HT and deck, I've come across this type before, there are some advantages, if it does the set will have a choke if not its unusual to be so high, there will be a fair old voltage drop.
