Vintage Sadler Burslem Glazed Teapot made in England

This is a vintage Sadler Burslem England "Brown Betty" style ceramic teapot with a mottled brown Rockingham glaze.
It features a dark brown base with a lighter, mottled brown and white drip glaze on the upper half.
The lid finial and rim have a gold-colored accent line.
"Brown Betty" teapots are traditionally made from red clay found in Stoke-on-Trent, Britain.
The specific manufacturer (Sadler, Gibson's, etc.) is often identified by an impressed or printed mark on the base as seen in the photograph.
****please note: the only flaw I noticed in this was a chip underneath the inside rim as seen in photos. This is not noticeable from the top with the lid on or the outside.
