I have an old Wagner Ware cast iron skillet (marked as model 1056T; measures about 7 inches inside bottom). This was given to me by my grandmother. 

Where the handle meets the pan, you can see a marked difference in material. It looks like the pan used to have some sort of coating that has now come off. 

I have another one (bought at a thrift shop) that has no markings except "No. 10  12 7/16" on the bottom. It also looks like it had a black coating and a more silver color is showing through on the round ridge on the bottom outside and on the rim edge of the pan. 

I keep these seasoned, but neither behaves as well as the Lodge pan I bought new a few years ago. 

So I'm wondering if they originally would have had some sort of coating. I thought not, but they just look so odd.
