Appears to be an adjustable spark gap. The two metal fins, one connected
to
each horizontally opposed points, are the inputs. The third point would be
connected to ground.

That seems to be most likely. Given that is has a wooden post, it is
almost a sure bet that it is used in an electronic capacity. There is no
way that it is any kind of a die holder or thread cutter.
