Now this is one very beautiful kris and a wonderful addition to your collection. I agree with Ian on age and that the hilt and scabbard look to be more than likely later replacements. I cannot tell from the photos and would like to know if those are actually nails or wooden dowels holding the two halves of the scabbard together? I don't believe the downward slope to the blade is unusual as I have seen quite a few other kris with this same feature. I keep picturing this mounted with a hilt more in line with the craftsmanship shown in the blade, maybe something with a bit of silver and an ivory pommel.
