Vtg Mid Century 18" Cast Iron

Vintage round cast iron pale jadeite green porcelain drop-in bathroom sink. The manufacturer is unknown c.1960s. The porcelain shows normal wear, there are scratches & scuffs, a few tiny pockmarks, some very light staining, and a little distressed porcelain around the faucet mounting holes 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.
