Congratulations!

This is an extremely rare find.

It is from south Sumatra. Usually it has more silver fittings on the hilt than yours (bands, nose, and sometimes an eye - see reference pictures).
Yours is the first "naked version" I have seen (unless you find traces from silver fittings on the hilt?).

Here is the only picture I know of it when carried.
It shows a chief from the region of Rawas, but the picture was taken in Palembang.
