This vintage replacement cookware lid fits the Wagner Ware Magnalite 12 inch skillet. I believe it will also fit the more recent GHC Magnalite chicken fryer and large stock pot or dutch oven, though I don't have either of those to confirm that. It's definitely vintage (not made by GHC) - very heavy with the Bakelite finial, side "ears", and interior drip ring. The lid is clean but has some minor age and storage wear, nothing serious. The inner lip is just over 11" diameter, exterior measurement not including the ears is 11-3/4 inches.
