very nice and serviceable sepukal.....
If the hilt and pendokok are not original to the blade, i am more inclined towards Palembang provenance.....
this one looks almost similar to mine... especially the "curve profile', flat ganja, lower gandik and almost flat ganja base

have you checked whether there's a needle in the hilt?
