That's OK Alan, you don't need to see the video on FB since Wijaya has provide us with more detailed photos that should give us most of what we need to see. (These photos might have still been in Moderation when you made you last comment so scroll back up and have a look
)
Like you the fluted body leaves me scratching my head as well. I have also never seen this before. The fanged face and the long hair down the back however seem to place this hilt in the category of Buta/Raksasa hilts. I can't say that i have seen this form in Sumatran hilts. If we just l look at the head and way the face is carved and ignore the fluted body for a second it is hard for me not to be put in mind of the more upright variety of these Buta hilts found in North Jawa/Cirebon. But i agree that the rest of the hilt creates a lot of confusion. Regardless, even if a bit stiff, the hilt is artistically carved and well executed. I suppose it is possible that it artificially aged modern creation, but it doesn't feel that way to me. I do believe that we both have the same "feeling" though that all parts of this keris have come from different origins, This surely is a keris that needs to be examined first hand in order to come to any conclusions and even then it could well remain a mystery.
