A cutlass: where from?

[ariel]

Here is a smallish cutlass with a " bird-like " pommel and a pronounced yelman.
Similar examples were shown in Elgood's Greece book and identified as North African (Algerian most likely). I agree wholeheartedly.
However, I am a bit confused with the scabbard. It is covered by a thin shagreen-like leather and has a brass chape of ( what looks like) North Indian/ Afghani open-work fashion.

Even though Afghani Navy can be safely excluded:-), the scabbard still nags me after many years of hanging on my wall.

Any opinions? Please put my hesitations to rest.
