It looks 100% Moro to me, not Malay. In fairly rough shape, but restorable for someone willing to put a little work i into it. If you were hoping for what is often referred to as a "twisted core" i seriously doubt you will see one on this kris, but it might have an interesting pattern once it is cleaned up and etched. It's not a bad kris, but it remains to be seen if it might be impressive.
