We have 2 Brown Porcelain Door Knobs Vintage items. The center bar is not with this set it is just the knobs and metal backs. They measure about 2 1/2" across the top front of the knob x about 2 1/4" in D. The metal building up to the porcelain on the knobs is metal and fairly well rusted. They have a marble like design in browns/blacks on the porcelain. 1 has ?black paint splatter on the side to back in one area. I would say they are in fair condition.
