Keris Bugis Raja Gundala

[A. G. Maisey]

It is a bit difficult to be too definite about blade origin when all that can seen is a part of the sorsoran, and the blade is being viewed wrong way around. A full length photo, with the gandik to the left of the photo would assist with identifacation.
That said, my feeling at the moment is that we are not looking at a Javanese blade, but I cannot yet see enough to be any more definite.
