This is an extremely heavy and well done item. It measures 14" across widest dimensions. The two large bowls have drain openings and rest on the shelf or table while the two smaller ones are closed and sit about 1/2" above the shelf. The only marks 4040 and USA. They were impressed in the blank while green and then glazed over. It looks like Hull but I think it is much heavier than Hull? Any thoughts on maker, value, etc?
