Yataghan inscription

[TVV]

While still in Bulgaria I acquired a yataghan in excavated condition. Can someone help with translating the inscription, which is the only thing worth posting? I am aware that the picture quality is horrible, and I will try to get a better shot, but it has been dark and rainy for almost two weeks here now.
Thanks,
Teodor

Hi,

I could not be sure about the date and the name of the sword maker. A better picture would help. The rest has a very common formula;

Sahib Osman (owner Osman)

Ya Muhammed, Kıl şefa'at
Ümmetindir

O Muhammed! Intercede on the day of Judgement on the behalf of him, who is one of your Ummah (community of believers).

Ah, um, could we get pictures of the whole thing, please?

Zifir: thank you very much for the translation. I have attached a picture of the right side of the inscription, which I believe has the date and the maker's signature, but it might be that it is simply not preserved in legible condition.

Battara: here is a picture of the whole piece, but it is hardly worth seeing - this is a yataghan in poor condition, discovered in a village in Bulgaria where someone replaced the original hilt (which probably rotted away) with this deer horn. It will need thorough restoration, but as of now there is no way I can export it outside of Bulgaria. If I ever do, then I would love to have you work on it.

Regards,

Teodor

Just a guess, I read the date as 226 and believe that it stands for 1226. (1810 / 1811 AD)

[Zifir]

Sorry, I could not make the swordmaker's name out. For the date, I believe Rather is right, it's 1226.

Thanks to both of you. The date makes perfect sense.
