Thats a good idea Sam, but I have started to unwind the outer layers and so far I have not come across more than a couple of hundred turns before another break. The breaks are caused by multiple "green spots" of corrosion presumably where there were pinholes in the original enamel.
You can see the "green spots" in this photo
This is the point at which continuity ends.
I am wondering now if the 11k ohms measured is almost double my estimate because of resistance through the green spots. My efforts to reuse what good turns remain may be in vain, and another spot fail as soon as a little current goes through it.
