Spring Bouquet pattern vintage china dinner plates, delphiniums & peonies floral

Unmarked vintage Edwin Knowles china in the Spring Bouquet pattern, with flowers in pink, blue, lavender, yellow, green. I believe this pattern is 1940s. I love those delphinums, that's a flower you seldom find on china patterns!

This is a set of twelve dinner or luncheon plates (9 1/4" in diameter) in excellent condition without chips, cracks or staining, showing little if any use.
