 This style of bifurcated hilt is usually associated with Sumatra, lots of stylistic variations, but in other places, including Sulawesi it is somewhere between rare and non-existent.

 Hello Alan,
I think you mean the so called rudus (a search here will show some examples), there are similarities but also a lot of differents. It's also called cojang see for example here:

I will take a picture from this one side by side with my cojang for comparison. 
The hilt was the reason that I was unsure about the Sulawesi origin since I never before have seen such a hilt by a Sulawesi sword.
Regards,
Detlef
