I was at a garage sale today, and picked up two cast iron skillets for $2 each, and a cast iron griddle for .50. The griddle is kind of rusty, and says it is Mexican Fiesta made in China (go figure). One skillet just says "11 2/4 inch skillet", which seems odd, that it wouldn't just say 11 1/2. The interesting one, though, is a Wagner Ware Sidney O, logo high, and on the bottom says 9c. This pan has a heat ring. There is a lot of crud on the bottom, but that's all it appears to have on it. I have been trying to estimate the age/era, and think it's from the 1920's-30's, but I'm kind of new at this. Thought I would ask here and see if anyone can help shed light on it. I appreciate any insights.
