Sumatran keris with original warangka.

[Athanase]

Hello,

When I saw this keris I immediately liked the original form of warangka.
The blade looks old and I didn't have this type of hilt (veiled Durga?). I don't know if it's really old keris but I made an impulse buy.
(The ganga is not separated from the blade)

I sure it's Sumatran keris. But where in Sumatra?
I found on internet that the hilt is typical of Jambi.
