Yesterday I received the keris and I think that I have to agree with Alan that the complete keris isn't a very old one but in all parts very good worked.
i have asked the seller about the history of this keris and he told me that he get this keris with some other items from a man who has been a surveyor in Indonesia and the Philippines before the second world war.
I have taken some close ups from the atasan as well from the blade. Someone has a hunch which wood is used for the atasan?
