Is this a Black Sea Yatagan?

Re: wrapping.
I see what you are referring to: some LB scabbards have a purely decorative panel of tightly woven thin leather ribbons, often black and green ( see attached pics) . Yours has a segment of non-patterned wrapping of a single ribbon that is very loose. My guess, this was not a decoration, but just a way of binding the scabbard to strengthen it.
Re. Anatolian yataghans.
T-pommel is specific only for Zeibek yataghans from Bursa area. This is one of the few infrequent yataghan patterns that is specifically recognized as belonging to a specific group ( see my earlier post).
The rest of Anatolian yataghans had garden variety ears.

Regretfully, I cannot decipher the stamp. Moreover, I cannot recall any LB with a bladesmith's stamp. If they exist, they must be very unusual.
