Don't know much about.. One has a hole drilled in the base, and may of been electrified at one point (none of the components are still there).. The piece that holds the shade is different on each lamp (and one is broken). The switch that controls the oil flow is missing on one of the lamps.
2 off the metal "tubes" inside are missing. I only have one set of shades.They have wear/ dust/ small dings.
