The good news is I have a continuous coil, I found the connection only 16 layers in, so have about an additional 5 layers than expected, it is measuring 11.8k ohms DC.
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.
