I have a working collection, and also a few in my shop.
I regret highly not buying a Lodge 20" frypan when they were in production.
First pic, right side - found that one in an old camp in the mountains. It was rusted and looked like billy hell. It cleaned up pretty good. My favorite for fried eggs, pancakes, etc.
I believe I have the same pan but not as nice as yours......yet.
People more knowledgeable than I(not an especially high bar) say its a Wagner.
