This weight does not fit comfortably into the category of Chinese White for me so wondering if anyone has any ideas, perhaps a more recent variation?
It is 6.5cm in diameter, flat polished base with little wear to speak of. The white disc is hand painted on the upper surface but it is not flat like the discs in Chinese Whites I have handled, it is much thinner, more concave and set far higher in the dome. The dome itself is higher and the blue used to outline the painted shape looks different.
It looks to me like it depicts a Bactrian Camel, native to the Gobi desert straddling the north of China and the south of Mongolia.
