Plas help id this Yataghan

[Oriental-Arms]

This type of Yataghans are commonly regarded as Balkan (The big wide walrus pommel ears). They were very common in the 19 C. I would be surprised to find an early 18 C. one. The blade could be an early one re-mounted in the 19 C. Yet, the quality of the silver work is 19 C. and I would expect a much better Caligraphy in the early 18 C. Another posibility is to read the date as 1280 (the short line after the figure 8 might be a 0) which makes 1863 in the Gregorian calendar.
