I don't think the decoration is N.African in style .
That leaves Indo Persia and the NW frontier as Tim has said .
Those look like architectural details behind the Peacock , those elements remind me of some N. persian rugs I have seen .
Not to mention the Peacock Throne of Persia .
I can see the Indian influence in the knuckle guard but the hilt is real oddball .
Whatever it is I like it !!
