with no markings... Is the toroid around the top electrically connected to
the wire in the middle?

It could be a feed through.. designed to be mounted in the wall of a tank.
BTW,  it looks more like it would hold off at least 50-60 kV if clean.  Nice
smooth curves, etc.  Probably designed to either operate in a vacuum or in
SF6 or oil...

The toroidal part could also be a guard ring, designed to make the
capacitance to the center very stable and well known.  It could be a
precision capacitor in the few 10s of pF range.  It would be used as the
"top" of a capacitive voltage divider.
