I tend to agree with Lew on this one. Lew, is the sheath definitely made for this keris? Does it fit perfectly? It seems equally well crafted as the blade and would seem a nicely made tourist ensemble, especially if the dress is original. What material is the white piece on the sheath? Is it bone or ivory?
It would seem to me that most keris from the northern peninsula tend towards being pamorless, so i don't think that is an indication of anything.
Is it just that patrems are unknown on the peninsula?
