I understand that Sadler produced the teapots for the Co-op Wholesale Society of Stoke-in-Trent to sell under the Windsor banner.
The early Sadler teapots were "Brown Betty" style, tall and shaped more like a coffee pot with possibly a marking found on the bottom.
It all began with James Sadler, who built a factor in Burslem at the heart of the ceramic industry in Stoke-on-Trent, and made a name for himself by making fine earthenware teapots.
Pattern was used on Sadler teapots since 1950, and discontinued in 2002.
You can find many variation of Sophie Chintz backstamps through those eras The base of this teapot carries the blue Windsor backstamp along with the embossed 'Sadler' which is identical in style to the Sadler ribbon backstamp.
