age

I inherited this skillet when my mom passed a few years ago. I remember her cooking bacon and eggs, fried chicken, and fish in it (I use it only for cornbread). I know it once belonged to my great grandmother, and it has been passed down through the years. I've searched for information online...

This is my first piece of vintage cast iron. My Dad and I had a lot of fun with the electrolysis bath! After looking at the unmarked photo forum I think this is an unmarked wagner. Do more experienced viewers agree? Any idea for possible time period for the piece? Thanks for your help!
