Vintage 1800s 19th Century Antique Solid Barrel Hand Wrought Iron Skeleton Key

Key is in solid structural & aesthetic condition, showing surface oxidization and a strong patina. When examined closely under a bright light, there’s a ghost of the number “3” still engraved into the bow, which appears to be the only marking on the item. It’s said to have originally functioned as a jailor/warden key. Sold as pictured.
