Second point for Kelhben here is a list of stamps similars to yours.
Astvatsaturian attributes these to Eastern Anatolia, based on the niello and similarities to niello decoration on arms from Georgia. It is a book full of great pictures, but the conclusions are based on the author's guesses, which she admits herself in the book. Not being able to read Russian does not really detract much, to be honest.
In Elgood's book I do not recall yataghans with this shape to the bolster as attributed to areas outside of Greece, and there are plenty of examples in the chapter dedicated to arms associated with the Greek War of Independence. But it would be a good idea for me to go through the book again.
