This knob pair probably came off of a Waterfall dresser. Each knob consist of three pieces: the center painted metal disc; the bakelite disc; and a metal stem or neck behind that.
The center metal disc of each knob has a short stem or neck and measures 3/4 inch round. The stem of this disc fits into the bakelite disc which is 1 1/2 inches round and 1/4 inch thick. It is a rich apricot or amber color. Behind the bakelite disc, the metal neck is 1/2 inch in length. Overall, the projection of the knob from the surface of the drawer is one inch.
This highly unusual and rare pair is in good condition. There are no cracks or chips in the bakelite. Screws will be included.
