The question of a strange pommel bothered me. Then, I remembered the Law of Nature:" When in doubt, read Astvatsaturyan's book on Turkish weapons"
Here are the pics of
Balkan swords; one has a pommel curiously similar to the one in question. Astvatsaturyan mentions that it was a common feature of the swords from that area: looking like Persian (90 degrees) and then going down. The Balkan attribution , by the way, would tie in the turquoise decorations as well.
