The only I can tell you is that this is 20th century. It can not be earlier due to its size and painting style, I think. The marks alone are useless, because if it is a well known porcelain painter, it is copied in great numbers. To verify authenticity you need someone who knows not only the mark, but also the specific painter's character writing and painting styles.
