Hi Jose,
Most coteng keris have lost their fittings over many decades. I've searched a little bit in old threads, have a look inside and decide!
I think that it's not relevant if the handle is from wood or silver. Do you mean pendokok or uwer? An uwer it will have originally but not a pedokok (selut).
