Primary=1.9K Secondary 7.6K.

2 metres of the wire measures just over 13 ohms so a good match to my finer gauge wire which I think I ordered as 46/47SWG. Measured the average circumference and a bit of excel confirms its about 16,000 turns which is about 8,600 ohms. 4,000 primary and 12,000 secondary.

I can actually see this wire so I am inclined to think the insulation is quite a bit thicker than the modern replacement and I am wondering if it makes more sense to use the thicker wire as I am fairly confident it would fit in the former.
