Hello Milandro, 
 
Spear heads are tough to place - this example seems to have a Sumatran touch to it but I'm far from certain. 
 
There seem to be pamor lines visible which should exhibit decent contrast upon etching. 
 
I believe the ensemble would be better of without the brass "selut" though. 
 
Regards, 
Kai
