congratulations with your yataghan!
What confuses me a little is the different bolsters (indicated as #4 in the first picture) versus all the above pictures.
Any data on lenght of the blades or the age of the 4 pieces?
I took the liberty to put them together and can not figure out the difference versus age....but that could be my limited knowledge
The blade is very nice and in excellent condition, with a beautiful stamp.
Specially if I would follow your case with regards to being an early yataghan
some interesting info can be found in this publication:

unfortunately I could not find anything to provide more insight in publications from the museums in Croatia, Bosnia, Serbia and recent ones by Zoran Marcov, Head of Department National Museum of Banat,
Maybe other forum members can assist in this most interesting topic...
