Ottoman 19th century, seeking help with identification
 

Hello everyone,

I'm an enthusiast of ethnic and antique arms from Latin America, and I recently acquired this Ottoman yatagan which I've been researching. I'd love to share what I've found so far and ask for your help to go further.
What I know:

The blade bears silver koftgari decoration with two cartouches of Ottoman Arabic inscriptions. With the help of AI tools I was able to read:

Tawakkaltu 'alā Allāh — "In God I have placed my trust"
Māshā'Allāh · Sāhib Hüseyin — "What God wills · The owner is Hüseyin"

The date 1274 H (1857/1858 AD) appears engraved after the inscription, following the horror vacui tradition.

The handle is bone with a characteristic kulak (ear-shaped) pommel. The bolster is copper with tulip-shaped carnelian inlays, all intact.
The opposite face of the blade carries a circular geometric maker's mark which I have not been able to identify yet.

My question: Based on the blade style, the kulak pommel and the maker's mark, would you say this is Balkan production — possibly Prizren (Kosovo)? Any help identifying the maker's mark would be greatly appreciated.

Thank you in advance for your time and knowledge.

Welcome to the forum Johnny!

Yatagans are not something I am knowledgeable about but what I can say is that I am nearly sure the handle scales are not from bone but from walrus ivory! ;)
And I guess that your nice sword comes from Bosnia instead of Kosovo but this is just a guess. We have a lot of people here who will be able to tell you much more than I am!

Regards,
Detlef
