Yannis, Zifir...thank you both for giving me the rest of the details, it is appreciated!
I too had come to the conclusion that the hilt and bolster were replacements. Grip on further looking plain bone. But for the price I paid...I have no complaints.
Probably a long shot, but any way of locating where the maker may have been from?

Here is the 2nd very long Yataghan....measures 94cm, pommel 16cm, blade has a T-back spine for 3/4 of its length. Also has koftgari inscriptions full length of both sides of the blade.
Again no attempts have been made to restore the blade.
