Untested unit. Does not fit a standard light bulb in the center. It is a very large hole. Standard bulb will fit in the lower 3 however. The switches click fine, but this is untested. I simply wiped off the outer glass. Otherwise this is as found. No returns. Very cool project here. I assume this has to be near 100 years old. Measures 10 inches across the top of the glass diameter.
