Hello,
I have an Erie #7 Iron Skillet.
This one is unique in that the middle bottom had some major pitting or somthing. It is very rough and almost looks like it was originally like that, like the way it was molded or something? I'm not too sure but it has been in my family for many, many years.
The only markings are
ERIE
7D
The "D" is about half the size of the 7
Thanks for all and any help you can offer,
Richard
