Asian Hallmark Help Please!

Hi there,

I have recently bought a silver condiment set including a silver holder and two cut glass lidded jars. The handle is designed like bamboo and the holders are intricate floral filigree, and this hallmark is on the base above the ball feet. Is anyone able to recognise this hallmark, and can anyone tell me the purity of silver for this piece from this mark?

Any help is greatly appreciated,

Will
