Hi. First post so bear with me. I found this pan at an estate sale. It appears to have had a long and tough life. The round handle is something that I would expect to see on a waffle iron but it found its way onto this pan. It was very rusty and has pitting both on the cooking surface and the bottom but after a soak in my electrolysis tank it will fry an egg without sticking. It is very heavy for its size. Some of which can be explained by the larger handle. It's not a collectible but an interesting item. Any ideas as to the foundry that cast it? Thanks for any insight.
