The black is tar. I have appropriate resistance across each of the windings and have appropriate voltages with 120V input (using isolation transformer and variac).
The ground wire should have connected to one of these lugs, probably the left one. The underside is perfectly flat, and there's a drop of solder on each lug, but no indication that any wire was ever soldered to it--and certainly there's no hint that a wire was broken off.
In the meantime, I'm probing the perimeter of the outermost winding, which I think is the secondary winding for the rectifier plates, and I'm finding nothing of interest. The cloth strip seems to be between the primary and the aforementioned secondary windings, but I can't find anything of interest there, either.
