Bugis Chieftain's Keris: does it exist?

[David]

Well Jean, of course they exist, we have all seen these examples before. Their existence is not what is actually in question here. But just because we assign them to the ownership of "chieftains" doesn't make it so. What i would like to see is photographic evidence of acknowledged chieftains with these keris in their possession or perhaps images of obviously non-chieftain types (perhaps just well off merchants or people of other status) with them. Who first began calling these "chieftain" keris and when? If indeed this type of ensemble was held by certain Bugis chieftains in a particular part of the Indonesian archipelago, were they the only ones permitted to wear such dress or could anyone who could afford such an ensemble own one?
Your second reply was not part of José's initial question, but certainly it brings us a little closer to the origin of these keris if by nothing else the process of elimination.
