Strange sumatran?? dagger

[Athanase]

Hello,
I recently acquired this dagger in a lot of various indonesian daggers.

For me the general look is similar to that of a Gunong, but the whole construction of the handle and scabbard (typical red wood and buffalo horn) is characteristic of Sumatra.
The blade is made of steel and the guard in brass.

Blade length : 16cm

Unfortunatly mice love the buffalo horn....
