Where is this sheat from?

[Sajen]

I received some days ago the keris with the Coteng hilt. The keris byself I will show later in a seperate thread since I think it's a very outstanding one. Until now it wasn't possible to open the hilt from the blade, I think this will need some days by candlelight!
But here some first pictures of the Coteng hilt. After some research here and in Spirit of Wood I think that it is a very old Coteng hilt, for example it's missing the hiasan badan carvings at the sides. It's a very plain example with a straight nose. It seems also that the hilt have get a coat of varnish by time over his old patination.

Please let me know what you think about this hilt. Thank you very much in advance and enjoy the pictures.
