Odd Visayan Ivory Kris Dagger?

[Gustav]

Here is one another, from Vandoo, similar to the one posted by Michael (VVV). As Vandoo or someone another wrote years ago, it resembles somewhat a hilt on a keris, which belongs to the Ashmolean collection in Oxford, there from 1637. So this type could be a very old one. There is also probably some superficial similarity to older Kastane hilts.
