Early Worcester Pair Tea saucers Rare Chinese lady pattern 1770's

Early Worcester Tea saucers
The pattern I cannot identify. It features a Chinese lady sitting with her attendant with lots of pots, flowers and foliage
They are not quite a pair as one is so slightly smaller than the other and one is more dished; see photos
Gorgeous little blue and white saucers / dishes
They are in excellent condition with no cracks or crazing and only one tiny chip on one; see photos
They have a correct early Crescent shaped back stamp
They date to the Dr Wall period of Worcester control
250 years old; amazing.
