This is a very nice, cast iron, Wagner Ware, “Krusty Korn Kobs”, corn stick pan. All the ones that I could find on the internet are marked with the patent date. This one is marked, “patent applied for”. I believe that would make this one older than the 1920 patent date found on the others.
This pan is in very good, used condition. Take a look at the pictures and if you have questions, please e-mail.
