I picked this pan up today because I thought I recognized it. The casting is very good, smooth, and side gated. No markings on the back, one end has a hole, the other has a hole shape, that's not a complete hole, just an indentation where the other hole would be. According to the yellow book, variation 3 indicates no markings on the bottom, appears to have a hole, or resemblance of one in each handle, and has all the right characteristics. Did I get a griswold no. 11 variation 3? And if so is the yellow book pricing accurate at $50-$70?
