Well, i know very little about these and had never seen one until this past Summer. In June i posted this one on the swap forum, part of a collection that a friend was getting rid of. By comparison it looks older and better made. The silverwork on your looks more modern and second-rate and i suspect it is not pure silver. I agree it is probably a newer piece.The styles, however, look similar and he described his as being Mandarin if i am not mistaken:
