Origin of this Yataghan? (With pictures!)

[Khelben]

Hi! New to the forum. The first time I tried to post it apparently all of my attachments failed to upload (Too Big) and I didn't notice. I think I am still in a "moderators must approve your threads" phase, and so I hope they will just delete that one. I have thus resized the images to fit the forum's limitations, and this time around it accepted them.

So, I received this Yataghan when my dad died, along with several other swords and Bayonets. He thought it was a Turkish Yataghan, but I suspect that was largely more of a "Turks had Yataghans" thing, because upon looking for something comparable, mine is quite different, particularly in the hilt.

I'm looking for some help identifying what the source of this sword could be, with it's more westernized looking hilt.

Is it a Turkish export to be sold to Europeans? Has someone replaced the original hilt with a new one? What am I looking at here? Have any of you guys seen one like this before?
