Spear / lance origin ?

[asomotif]

Nice one. Danny has got a sixt sense for these pieces.

The lance head itself makes me say Java.
The silver collar is found allover the archipelago and beyond.
But the silver strip around the shaft is new to me and I can not place it in a certain area.

It was offered as being from Bali, was there any info from the seller that points to that origin ?

Silverwrapping on the bottom of the shaft can be restored, but at the present silver prices it would propably double or triple the costprice

best regards,
Willem
