This was my attempt at restoration. When i owned this piece it had half of the bone guard present. So I made another bone part to try to match, then replaced the missing guard with a twisted double snake made of chased silver with each end in the form of a snake head with copper eyes. I chose to do this to match the other parts of the kampilan hilt mounts.
Years later, a new dealer took all of that out, did their own bone, and got rid of any guard.
This is one which I wish I didn't have to sell off at the time.
