Please more information about this keris

[sirek]

After some cleaning an a pineapple-bath, I would appreciate to hear your comments/information about this keris.

The buntut is made of horn.

There is a leather strap under the warangka, it sits there for a long time I guess.
I do not know if there is damage underneath it, I cannot remove it it’s completely stuck (And I do not want to damage anything).

And I would like to know: is a strap like this original, or is it home made?


Thanks in advance for your effort
