I picked up this unmarked "hammered" piece on eBay for what I think/hope was a good price, $6 plus shipping. I'm guessing that it's from the Chicago Hardware Foundry, based on various things I've seen on the Internet. I can't find any solid information on that foundry, though, other than they bought up Favorite's patterns, etc. in the 1930s, so I would very interested knowing more about the foundry and this pan if anyone can share their insights. I ran across some similar "hammered" pans in sizes 3 and 7.
Here it is. It looks like it will clean up nicely.
