This is a Sadler, English dark brown Brown Betty pottery teapot with a high glaze finish from the 1960s, made in England.

The Rockingham glaze teapot measures 6 inches high by 9 inches long by 6 in diameter and holds 6 medium cups of tea.

The tea pot is in very good +++ used vintage condition with no chips, cracks or even crazing, and the interior is clean an unstained.

There are a few manufacturing or glaze flaws and a few surface grazes in a small area that don't detract...I am just being picky.
