Note that there are 2 lights (main and a small one inside the meter). The switch in photo #6 controls the small light inside. The dial spins when the lights are on.The speed of the dial depends on the wattage of the bulbs. It will spin very slowly with a low wattage bulb.
I'd recommend to just use a low wattage bulb however as I'm not sure of the max wattage that would be safe. Measures in total 19.25h (to top of finial).
