the main bowl part looks like a solid sheet as i can find no seams. It has been hammered to a six sided shape. The base of the bowl is smaller as it widens as it heightens. There is a little peeling on the underside. I cant tell if there is actual damage spots or if it is just detergent spots.I dont know anything about how to polish it so i am going to leave it be. the top of the handles go straight out and then down. The manufacture stamps and the number 275 are real clear.
