Copeland Spode Byron Series, quartered sandwich plate No 1

 

Copeland Spode's quatered plate from the Spode's Byron series No 1 c1931 - 1969.  It is almost octagonal in shape,  and  divided into 4 sections.  Most of the sellers date these plates to the 1930s, but then they would.

 

This backstamp was used from circa 1891 and into the next century according to this website.

Nancy and her Daily Dish blog knows how to take Spode seriously.
