My great-great-great grandfather was the last Duke of Pineung in Aceh (now part of Indonesia). He had 5 wives and gave each one of the an identical tea set, probably purchased them in the Netherland.
Non of other 4 sets survived. But one did. It is belong to his second wife and passed to her daughter in law and then to my mom. They used to use it on daily basis, but not anymore. It is in a very good condition.
I looked at it and it got the stamp of Pirkenhammer Czechoslovakia 1920.
It only have 5 cups (i suspect one is lost) and the sugar bowl topper is lost.
I hope to get apprisal of them. I hope somebody can help me.
