The third wire on the antenna fiberboard is a single trace that lays alongside the edge of the racetrack loop. One end of that wire is terminated and literally buried into the fiberboard where no electrical connection can be made to it. Looks like it was punched in with a tool. The other end is connected to a wire which presumably is the wire that would serve as the external antenna lead in.
Do you mean that single lead would go to an antenna, or to an earth ground? It wouldn't be possible to connect that isolated track on the antenna board to both an antenna and an earth ground.
Thanks again.

I assumed that your back looked like this one from the ARF thread. It appears to have 4 connections, which would match what's shown on the schematic.
Basically one loop with another around the perimeter. But maybe I'm seeing things. If that's not what's going on there then I'm a little lost myself, because that's normally how an antenna matching transformer is designed. Let me go study that schematic again.
