Vintage mid-century round cast iron regency blue porcelain drop-in bathroom sink. It is marked American Radiator & Standard Sanitary c.1960s. The porcelain shows normal wear, light scratches & scuffs, a few pockmarks, a light outline from an old faucet (would be covered with installation of new faucet), and a little distressed porcelain around the drain and the overflow. The original stainless steel mounting ring is included as shown, it will need the under-mount clips for installation. Overall good, salvaged condition. Please be sure to look over all of the pictures as they are the best description. Feel free to ask questions when needed. Thanks for looking!
