I took as an example a wonderful sword just sold by Oriental-Arms.

The blade is of a Persian shamshir, but the handle is of typical Ottoman " bulbous" form, and the crossguard has long Ottoman quillons.
The scabbard is also of Persian pattern ( no wire stitching) as well as the suspension rings ( oval and integral with the fitting, rather than free rings, customary to the Ottoman pattern).
So, the question: is it Ottoman or Persian?
Turks used shamshir blades on their swords and called them " Adjemi Kilic".
But this one has such a saturated mix of Turkish and Persian elements, that I just do not know how to attribute it.
This is not the first one I see, and the question pops up every time.
