This vintage Mid Century replacement cookware lid fits the hard to find Revere Ware stainless copper clad 4 quart saucepan, as well as the 8 inch inch skillet. The inner lip measures 7-3/4" diameter and will actually fit any pan with a rim diameter of 7-7/8 to 8-1/4 inches. It has some very minor, hair-fine marks from cleaning and storage.
