A bit of Googling will find several calculators enabling you to determine how many turns of a given wire diameter will fit into a given cross sectional area. Try various wire diameters in the calculator until you find something which looks sensible. You can then multiply the figure by 0.25 and 0.75 to get the number of turns in each winding.

I have tables showing the diameter of ECW over the insulation, but they're for SWG wire, not metric wire diameters. Might give a clue though.

Does the original winding have inter-layer insulation, or is it just burnt turns I can see?
