help with large willow pattern dish
I have a large approx 14 inch diameter willow pattern shallow dish/ plate. The pattern has a willow tree, a bridge with three figures crossing, a boat, 2 pagodas, a garden a fence and two birds in flight. It has no date or manufacturers name on the back, but it does have the number 6 or 9 printed in blue and the number 10 or 16 impressed in it. There's another impression on the reverse, but can't make it out. looks like a thimble shape with maybe something in the middle of it. Any ideas?
