Sumatra keris (bahari?) with strange pamor.

[Athanase]

Hello,

Here is an old sumatran keris with a unusual pamor (for me), but this is my first keris with this blade shape so I don't know much about it.
The blade isn't in good condition.
The blade is not in a good condition, I just clean the blade (roughly superficially) by rubbing with WD40 and a rag. There was a sort of dark wax in the hollows of the blade, for the moment I did not remove it.
The blade measures 40cm

The selut (silver?) Is broken, and the handle very worn because looking very closely at the head of the jawa deman I could see very fine incisions filled with a black substance. These engravings are very simple and draw loops but impossible to take pictures.

The pamor makes me think a little about the Javanese pamor Pari sawili but there is still much difference.
Do you know the name of this pamor and its meaning?

PS : Sorry for the quality of the pictures. Either the blade was too white or shiny, or too dark. It's the least blurry pictures I've ever done to see the pamor.
