This barrel mug was made from a 1962 Duncan mold design. The handle came in a set that included a "Hillbilly Handle" and "Nude Handle" mold. The nude handle measures 4.25" tall. Production number is: "DM 1001 -- Mug Handles" and the barrel mold is: "DM 33 Beer Mug Mold" (which has a wood grain pattern and bands at top and bottom). As a hobbyist set, glazes and design features vary.
