I have a micrometer and could measure the wire but you can probably get away without one.
Wind say ten turns around a rod, close spaced, and measure the length of the coil, then using high level mathematics divide by ten.
This should be easy to do with a coil winder.

I am thinking of getting an antique coil winder going so would be pleased to know all the trials and tribulations that you manage to solve.
