Gold Keris - Malay with Bugis Influence?

[Battara]

Greetings folks.

Rarely do I have much to contribute or ask on this side of the forum, but today I do.

I need your help on identification of this piece - from where, age, purpose, and anything else you see and can help.

The dress is gold, the wood has flashing grains, and the selut is brass. I figure that the blade is older than the rest.

Thank you.
