I have examined this in all aspects it rings true, the biscuit is correct the colours are right the mark very good and there were some very unusual pieces made during the Xianfeng perod this being one of them. There is genuine wear to the body as shown in one image and finally why would anyone copy this design and get it so wrong.
The dish is one of different sizes usually made for high ranking concubines and this is a smallish one measuring 5 1/8 in or approx 13 cm diameter..
