I recently started to buy real cast iron to cook with. I bought a Wagner no 6 baked it and seasoned it and hung it on my wall. Today I came across a better no 6 than I have so I bought that one. Here is the question there are four differences in these two exact same pans. The O is different from one to the other the depth of the Wagner Cast name is different the numbers on the front of the handle are different scripts and the weight one is three pounds and the other is four pounds. Any information on why this is would be greatly appreciated.
