I have to say that the blade itself looks very Moro to me, though the greneng is very Indo. But it seems that i have seen this more Indo looking greneng on other Moro examples and it may just be something retained on early Moro pieces from it's Indo origins. The sheath on the other hand is just a larger version of a Jawa gayaman style and the hilt doesn't look particularly Moro to me, so i would vote for a Moro blade redressed somewhere in Indonesia.
