since you bought it from Ron, why don't we ask our good friend Ron for his opinion too? (He must be lurking here sometimes too I guess

And you're right, Ron is a great seller... in fact I've been considering to buy this keris too but you beat me to it. Congrats .I like the hilt. doesn't matter if it's made from bone or other wise. it still is a v handsome hilt to my eyes.
