I have a #11 Griswold skillet similar to the one on page 20 of the Blue Book but markings are a little different. There is no "Cast Iron Skillet" across the top. Below the Logo it only says Erie (no Ohio, U.S.A.). It looks like the #8 on page 21 but does not have the quotation marks around "ERIE". My question is, is it common to have variations on the markings? This was a freebie piece in poor condition. Setting upright in a leaking barn full of water, bad pitting on the bottom of cooking surface, so not a collector. I love using Cast Iron to cook but am a preschooler on collectables, just got Blue and Red Books from Greg yesterday.
Thanks, Mike
