Hi Rick,
Welcome to the forum!
Like Rick noted, it's a kris from the Philippines, around 1900 would be my guess. I think it's from Mindanao but I am not sure but we have members here who will be able to tell you more.
You need to clean the blade from rust, the blade will benefit from a good clean-up. To restore it to a complete kris would be what the most of us here would do, adding a fitting handle and clamps would make this a beautiful kris, the blade has beautiful inlays! The inlays have a talismanic purpose. See here for kris with talismanic inlays:

Attached is a very similar blade from one of our members.

Detlef
