Poole Pottery freeform shape 358 floral handpainted dish 12 1/4 inches vintage

A pretty freeform dish (shape 358) by Poole Pottery with handpainted floral designs. The backstamp was definitely used from 1955 to 1959, but this piece may be from the 1960s. Some have labeled this pattern KP but I haven't been able to confirm. Measures 12 1/4" long and 4.5" wide at the widest part. The only defects I see are some marks on the bottom; no chips or cracks. Smoke- and pet-free home.
