In would be most grateful for any help in translating the cartouche from this Ottoman yataghan.

Thanks in advance!

Hello and congratulations for the lovely piece!
In the first round window, I believe I can identify a date: 1290 AH (1873 AD).
But that's as much as I can help.
Good luck with the rest of it!
