This, I think, came from an old house and was in the billiards room. Large at 20 9inches by 20 inches. Very heavy and I think steel. Hangs by 4 chains from hook on light fitting. Think it is about 1900 as came with gas fittings originally. Steel casing has 1 or so small bends easily hammered out. Metal plates are covered in original paint.
4 triangular plates fit in groove but need a bit of working out which one fits in where. Held in by 4 missing nuts. Either get the nuts, or cut off scerew ends and simply silicon in. Or take out screws and fit with screws and nuts to fit. Not hard to do.
Can be snooker light, pool light or light for anywhere that has light fittings to hand from. Industrial look. I have had this years and need to move on for someone to resurrect and use. Easy access glasgow city to collect.
