Hello Jose, Not trying to be the wet blanket here, but the only way that your example could be the one shown in the photo of Datu Piang would be if the orange swassa filigree section has been replaced. Both hilts are very simalar but not quite the same. This is just my personal opinion on these hilts and I am by NO means an expert on kris or for that matter anything else.
I will leave with a question though. Could this possibly be another of the Datu's kris but just one that is more ornate than the one in the photo?
Best,
Robert
