I'm wondering if anyone knows anything about this pattern from Johnson Bros. It has a lot of crazing so I'm assuming its old. I would like to know the date of this pattern and if there is any value in this platter. It's a blue/grey with swags. It measures 12 1/2 inches by 9 1/2 inches. It says Villiers, Johnson Bros, England along with the number 15 on the back. In my research I did discover that the pattern has been discontinued.
