This is an Ellgreave, a division of Wood and Sons, England large 4 to 6 cup or 36 oz teapot with a pretty design of an almost Jacobean floral design on both sides with gold trim.

The slightly panelled English ironstone teapot was made by in the 1950s.  

The teapot measures 6 inches high by 9 inches long by 5.5 inches in diameter and is in excellent used vintage condition with no chips, cracks or any wear and looks like it has lived in a china cabinet. Such a pretty pattern.
