nechesh,
No, I know less about this than you do. The horn could go through the whole Coteng, but I cannot tell. It has a grayish appearance where you can see it at the entrance area for the peksi. I was hoping you good folks could tell me.
Battara,
18c, wow!

Strangely enough, it is on a 20c Panjang. I find Guruda hilts fascinating, so I bought this Keris because of the Coteng... not the Keris.
Thank you for both your knowledge and input!
