Tombak for identification and sharing

[Sajen]

Recently coming this tombak to my hands, nothing special our outstanding and not in the best condition, the shaft is shortened, the tip of the blade is broken away and the complete blade was painted over rust with golden colour. Otherwise it's in great condition!
It's a pamor blade, one side I've cleaned from rust rudimentary with a rubber gum for blades. The methuk seems to be separate and the ferrule is from brass. Would like to know from where exact it coming, Java?, Bali? or Sulawesi (Bugis)? I am very unsure about this, any thoughts?

Here some pictures.
