A scarce form to find! This is an unusually small cup and saucer. I've not been able to find another example of this size and shape. The cup is 2" high and 2-1/2" wide. The deep saucer is 4-5/8" wide. According to the excellent Transferware Collectors Club database, this Chinoiserie pattern is "Pheasant on Rock".
Both pieces are in excellent condition (excepting some "in-the making" roughness to the cup's foot). No chips, no cracks, no crazing and no repairs. Both pieces ring when tapped.
The saucer has the "Ashworth Real Ironstone China" impressed mark, but with a Morley pattern number: 4/255. These marks date the set c1860. Morley acquired the original molds and designs from Mason's. Ashworth succeeded the Morley & Ashworth partnership in 1861.
