Some of the best I‘ve ever seen

[milandro]

Only 3 of these pieces seem to be Balinese , you have a piece with an hilt from Madura (with the donoriko hilt) but seemingly a Bugis sepukal blade and a Bugis sarong , that hilt is certainly incorrect on this kris, and one from Sumatra (blade is not visible but the Java Demam grip should point in that direction).
