Unusual Sumatran sword, maybe Mandailing?

[Dajak]

Hi Michael is that an coin under the handle we see this a lot in Borneo the motif under the handle I never did see that used in Sumatra .
I will go back to the museum as soon as I have time to make an full picture.

If you visit the Netherlands I can take you to this museum depot that closed in 2004 .
It has an old collection never see weapons like it before.
