mariusgmioc, thank you for reply. I compared some examples from Astvatsaturian's book and think the same about the date. But I may be wrong.
If i'm right, another one may be from 1824/25, but it was very hard to read between the rust.
I will do my best and give them back their lost beauty. Conservation is about knowledge and practice, and before I will touch them, first I must know everything about this type of weapon

and about these two.
