The lightening bolt is a two piece face lamination, tapering on all four sides down to the base. Captured in the lamination is a 3/4" threaded rod, that bolts the base and the leg together. The polychrome was probably artists acrylic, with a lacquer top coat. Visible in the larger image, center of the top, Boom!, clear epoxy and large metal flake, filling an incised area. I've used automotive finishes, candy colors, metal flake, on other pieces, usually as design elements, as here.
