Vintage Enamel Pan

A tidy looking pan measuring 11" across and 4" in height. I was never sure of the original use for this pan, because it does not seem to be a washpan or basin type since it does not have a hole for hanging and is a bit small for the purpose. I have wondered if it was the bottom to a roaster because it is quite heavy, but it does not have handles. Someone told me it could be a pudding pan. There are no dents but there are some TINY nicks and a few scratches that do not reach the dark base material. I need your zip code to calculate the postage.
