Duke, I saw that post when I was trying to research it here. I agree with the similarity. Just don't know if they had unmarked pieces, but if so, it could be a good bet. The hammered effect reminds me of Wearever and perhaps Club pans. I believe Wearever made some cast aluminum cornbread pans, but the ones I've seen all appear to be single row pans.
Cheryl, believe it or not, you're looking at the result of 3 applications of Carbon off so far. When I say the seasoning was thick, I'm talking 1/8-1/4" on the bottom (couldn't tell it was hammered) and the corn stick kernels were almost completely filled in. I'm going to keep messing with it just because I'm stubborn, lol.
