It's a klewang and a pretty rare one with it's rounded riccasso. I happen to have one just like it but with a laquered scabbard the blade exhibits the same exact pamor but mine has been polished up so it's harder to see. I think the pamor is called grasshoper teeth or someting like that? Will post a pic of it when I get home tonight. Bill notice the klewang at the bottom of the photo similar to yours but with a flattened riccasso.
Very nice piece
Congrats
