Heavy duty stainless steel lid that was MADE IN THE USA! This was from my moms set that she received in 1959. For some reason the lids were saved when she decided to update her cookware. I'm not sure of the size pot it fits, but I think it's for the 3 QUART pot. It has measusured at the interior where the lid fits on the pot. Farberware has kept the pot size standard and should fit any pot made after 1959. Make sure to measure before purchasing. Will last forever!
