Hi James, Looks magnificent. This looks 20th century to me, but from these pictures I am not sure when. Rather second half, I would say judging from the bottom and mark. The mark itself is a "Jingdezhen" mark used only later in the 20th century, and the style of handwriting was not used in marks early on, thus it seems to confirm what I said above.
Can you check with a magnifier whether it is hand-painted? the individual brush strokes should be clearly visible if it is.
