Here we have an original Standard brand toilet tank lid in white. Model number for the lid is “F4043″, and these were commonly found on close coupled toilets from the 1950’s and early 1960’s. It measures 20 3/4″ by 8 1/2”, outside edge to outside edge. These lids have been cleaned, but may have light scuffs/paint residue. They will not have chips or cracks. Several available.
