Welcome to the forum Yanni,
agree with the others that this is a very nice kris. A careful restoration would be nice and I think that Jose can help you by this.
But I have the same question as Tunggulametung and David: Why do you think Jose that this isn't the original wrapping of the hilt? It seems to have a good age and patination.
Or do you think that it isn't the original hilt since the blade seems to be a datu chieftain blade and have had by time a other hilt?
Regards,
Detlef
