I was going mention that that primary coil isn't very critical as it is used just to couple the rf energy to the secondary. The secondary is part of the tuned circuit, primary isn't. You could if you wanted to rewind it like the other coils with the primary on top of the secondary. Or you probably could use an ant coil from a model 20 or 70. The only thing that matters is at the tuning cap is the same value in mmfd's. Then it will tune the proper range.

figure out what all those squiggly meant.
