I just posted a suggestion for you in your Warwick thread.
In the case of the 42-720 coil, I was able to unwind most of the windings of the AM antenna coil primary, so I could make a fairly close estimate of the total number of turns.
I was going to get out my micrometer and measure the size of the old wire, but as usual for me, I was so focused on rewinding the coil that I forgot. The original may have been 39 gauge since the total resistance ended up a bit off, but the coil should still work as the antenna primary isn't as critical as, for example, one of the oscillator coils.
If this set had been AM only, or if this coil had been only for the AM band, I would not have hesitated to try a P-C70-A universal antenna coil from Antique Electronic Supply.
