Ethiopian ''dhal'' shield ??

[francantolin]

I was trying to identify what kind of leather it was made of,



It is not transluscent ( but the backnis blackened )but thick clear leather with ''granules'' under a layer of black lacquer (?)
Can it be rhino ? Hippo ? Buffalo...

Weight is 1,2kg and 42cm in diameter.
