Being a tripod it’s a good thing that this thing is heavy. It ain’t going to tip over.. I don’t polish lamps or anything else for that matter in general! I did check this with a magnet there is no iron in this at all. It’s not plated either. It weighs right around 10 lb. The harp and the knob on top came with it and they match.. I do not know who made this.. I just have some ideas.. If you have any knowledge otherwise please let me know! You can see the heights of various points in the photographs.. Feel free to make a reasonable offer if you like.
