Vintage 1920's Wagner Ware Sidney-O- retailer 1088 B Deep 10'' Skillet No. 8

My friend from S.C. gave me this when she moved away . It had so much burnt grease on it that I think I might have put it in a pit fire to remove it at one time . I wanted to read the mark on the bottom . This was years ago . Now that I'm moving and trying to sell the heavy things I see that it is a retailer valuable skillet ! There is one on Etsy now for $165.00 and $ 8. shipping .It is seasoned though . This one needs to be .
