Hello to all! I am not a collector just a user new to cast iron and this website. I found this skillet hanging in a barn in the holler and this was my first acquisition. After cleaning and using it, I was HOOKED! Light, smooth, etc. Anyway, after scouring the internet on my own, I thought maybe it was an unmarked Erie 2 series. I thought it has all the same characteristics. There are some ridges that look like they were cut into the sides of the handle where it meets the pan. Some sort of grips? I have been told now there is no such thing as an unmarked Erie so now I am still left with the original question. Any ideas what this pan is and possible the age?
