Hello Charles,
Seems like you convinced Santa!
Congrats, that's another well-above-average pedang for your collection!
The Sumbawa knife is a really great example - I also wanted to bid on it...
It certainly makes sense to drop the name pakayun which was another error by not well-informed outsiders. Murut is a name attached in colonial times for several ethnic groups (the Lun Bawang possibly being known best); it should be dropped since it seems to be widely regarded as offensive.
Can you tell whether the parts of this piece (especially those of its scabbard) are from different periods? What animal is the white hair from?
Regards,
Kai
