IMO from the picture i can see a nice Garuda sumatran hilt: not very very old but surely old! (more than fifty). The quality of hard (but not heavy...i suppose) strong wood is absolutely nice! The quality of work is good too. In my collector's hits experience is not so difficult to find a hilt like this but...I don't have a Mendak like this
(maybe because in Bali or in Yogya is rather easy to find old sumatran hits...but is really difficult for me to find nice sumatran mendak alone (without a blade under and a hit above).
