This is my 1st time on any forum. Even though I'm a regular to this website. I am pretty much able to ID most CI I come across. I even ID for a local antique store. But I have a 7in skillet I can not ID. If you know what a series 2 erie looks like then you know what this pan looks like. Every single detail is the same except for it has a gate mark and it doesn't have anything else on it. This pan has been in my family for about 75 years that I know of. It hasn't been used in many years and I had never cleaned it, until this past weekend. It had quite a bit of build up on it. I was 100% sure I would have found 'Erie' under all that crud. And I would have never knew it had a gate mark. Build up was that bad. If anyone has any suggestions or ideas I will be glad to hear them. Thank you in advance.
