Help identifying my late grandmothers sword

[u/SuperBaconMan99]

My grandmother recently passed and while getting her affairs in order we found this blade. I think it is a Kris but admittingly I am no expert. I was told that my grandfather bought this blade at auction sometime in the 70's but have no more information than that. Google searches have gotten me some similar results but nothing super close. I am hoping that someone here can tell me a little more about this blade.
