Thanks Tim, I think you are right. It could be one of the possibilities. It does look about similar with the image you posted. TQ. To be more specific, this pusaka is a laminated item.Thickness equivalent to about 2.5 inches whereas Keris laminated blade is about 'a small portion' of an inch. I am sure, this item took real, really longer time to be accomplished. It must be something specially sacred.
To you Nechesh, I got this thru somebody, who really in need of money. Since you insist, I will tell you the ghost story

. I was told, this item was brought from Palembang(Indonesia) to Malacca ( 14th Century ?) by the first Hindu Sultan of Malacca, Parameswara ,who later converted himself to Islam. It was supposed to be one of his most important final inauguration tools (??) . Nechesh, is nice listening to this story but do not get carried away

.
Is it a Hindu Gandhar (Gadhar ..spelling??) of the Indonesian Pajajaran/Majapahit period?
