Thanks Ben, your close-up photo does in fact reveal your hilt to be tridagna. Sort of an aside to the topic, but nice to know anyway.
I still am not convinced that Willem keris has been artificially aged based on your comments. The obvious fact that many new keris are treated this way does not prove that this is one of them. Many keris are mistreated in their long lifetimes and don't look exactly pristine, or even as good as your examples, after many years of washing and staining.
That doesn't mean that there is absolutely no possibility that Willem's keris is a new, aged keris. The folks who do this stuff have become very good at it, no doubt. I just don't see how you or anyone else could possibly be as sure about this as you seem to be based solely on these on-line photos.
