Thanks!
Sorry for bothering you again, but this pic looks more informative than the earlier ones.
What is the width of the blade by the handle vs. close to the tip? Is there some kind of yelman-like configuration?

I also do not see much similarity with the " steppes" ( nomadic) swords. It looks at least a couple of centuries younger. I would not exclude some Ottoman or even Zaporozhian cossacs Kilij/pala.
You can look for books by Denis Toichkin ( in Ukrainian). I am not feeling well these days ( nothing terrible or dangerous, just some hip muscle tear), stay in bed most of the time and have codein with every meal and any occasional snacks. Cannot think very straight and am useless as a " consultant":-(((
Sorry.
