Interesting Indonesian Knife...Siraui or Not??

[CharlesS]

At first glance I thought this knife was a siraui, but it clearly is meant to be held edge down, even though it fits into the scabbard very similar to the way a siraui would.

The hilt is horn, as is the wrangka, with the remainder of the scabbard being carved wood with a bone chape and silver bands.

Note also the unique brass bolster.

It has seen age and wear, but I don't think it's more than 50 or so years old. It measures 14in. overall, with a 7in. blade.
