And soon as I find the time I take pictures from dugong keris handles and post them as well.

Detlef, i am curious how you know that the material on your keris hilts is actually dugong and not some other source. AFAIK there are no really large pieces of dugong ivory so i understand why Thor is skeptical.
I do agree that this looks more like ivory than bone to me also. How large is just the hilt of this piece?
