It is marked as shown in the photos: FRANK W. HAY & SONS, JOHNSTOWN PA. You can see a raised line around the stem of the pan on the bottom. This is typical of these pans. It is a line that is a result of the casting process; it is not a crack.I have cleaned and seasoned the pan with one coat of lard. The first three pictures are after seasoning, the other three are before.
