Hi Vandoo,
Thanks for youre deep going explanation on the hilt.
Personaly i also have the idea its a verry old one , because of the signs of wearing and handling this one.
It,s not realy big , about 8.5 cm but it has a nice weight .
what kind it is , i will just say if some one ask its sea ivory , but for know its standind quite nice on a madura keris at my home
Regards,
Danny
