I'm a new member to this forum and just happen to have the same exact model you have. The gate mark is in the same position and I believe our skillets may have come from the same place and time period. Would like to compare notes as I believe our skillets are antiques and in my particular case the skillet interior is ultra smooth (overlooking the pitting). There appear to be some casting flaws on mine and makes me wonder why someone would polish up a skillet with casting flaws. It's not worth much other than a skillet to use, but an interesting piece if it happens to have come from a small foundry that made knock offs before they went out of business. Sure would like to know more and have more pictures, dimensions and weights if anyone is interested.
