It is a European variant of the so-called “ Mameluke sword”. They appeared after the Egypt campaign of Napoleon and became very popular. The idea that it belonged to a Turkish officer likely stems from the impression that the blade carries genuine” Islamic” inscriptions. However, they are just a meaningless array of curved lines, an imitation of the Islamic script. Such a decoration was often seen on European blades, especially on the Hungarian ones. However, they do not provide a clue to accurate attribution. The blade may be ( not certain) made of mechanical Damascus ( pattern welding), but polishing, etching and better pics are needed to be certain.

Furthermore, European swords, unlike Oriental ones, almost always had steel scabbards. That was good from the point of view of longevity, but bad because they dulled the edge. Metal plate covering upper side of the handle and the pommel is also a typical European feature.

I cannot be sure about the organic material of the handle, but cannot see anything pointing out to elephant or walrus ivory. The upper part of the organic part has multiple slightly elongated black components. If real, they would suggest just long bone ( bovine as a rule): remnants of blood capillaries on the surface, the periosteum. If there are different pics, they may prove me wrong, but walrus ivory has two components: homogenously white/yellowish on the outside and more inner marbled ( oat-meal like) layer.

I would agree with the dating: late XIX- very early XX century.

Overall, a nice European officer sword.
