S.E.A? sword

[DaveS]

I can't seem to find any pictures of this type of sword anywhere that I've looked, at least in my limited library. I'm sure that it's Indonesian, possibly from the eastern part of the islands. The blade is heavy, 20 inches long, 27 inches overall, and a little less than 1/2 inch thick at the base. No scabbard Borneo also comes to mind as a potential area. Anyone seen one like this before..........Dave.
