I do not have the wire size, however, if an end of the primary can be extracted at either solder lug it can be measured. Better off getting the correct wire size in event turns count fails. But using a magnifying glass and a wooden stylus the count can be correctly made. Do replace the celluloid liner, PEET or PETE is fine and can be salvaged from a bottle or bought on eBay. Measure the thickness of the celluloid for the nearest value of PEET. I have also used acetate salvaged from a wrap of a lampshade protection. Rotting of the celluloid is a principle cause of the coil failure.
If the wire size seems to be slightly smaller than a known size that can be accounted for as the wire was wound under tension. Do allow .0005 for enamel

You will find cleaning the form thoroughly then dunking into hot bees wax until bubbling stops and the form is HOT there will be a thin film of wax. The wax will grip the wire during winding and help create a more even lay.

Confirmation of the turns can be made by multiplying the wire sized by the distance the winding occupies...
