Looks similar to a shamshir but many examples of those have straight quillions. Photo of blade would be helpful.
An example of a Shamshir

I think it's this one:
This is an Ottoman shamshir with a sabre blade (common shamshirs have more curved blades). It's from the late 19th century. If there is an engraving in the blade, it will tell you the precise origin.
The "metallic" parts in the hilt and the scabbard should be an inlaying of silver. I think silver can be polished even if it's so badly damaged as yours.
