Hi Ian
Actually in Taiwan it is far more complicated. It was actually bought in China not Taiwan so it is very complicated. Although Taiwan is still a part of China (that is all under debate as you know of course). However I have been hesitating to take it to the museum for that reason (national palace museum). But as I am now fairly sure that it is a reproduction, (but I think a far earlier one than the norm) I am not so worried. One thing about Taiwan is that the law is very flexible depending how they get up in the morning or if the enforcer of the law has just had an argument with his wife. It is very flexible depending on who is enforcing it, and every department always sends you to another department.
I'll go to the museum on Friday.
regards
Douglas
