This style muffin pan was produced by many, many foundries, late 1800's thru early 1900's.... and beyond..
Without markings, we will never know 'who dunnit'... :(
The Lodge pans, we feel more confident in identifying... due to markings and cross referencing with catalogs....
The Atlanta Muffin Bakers were listed as 11 cup and 12 cup !
Now I'd like to see an 11 cup! (ASW Catalog #6 in the catalog sticky at the top of this board)......
