Since there is no characteristic ornament on the blade, I think about Boka Kotorska by the design of the scabbard.
Scabbard is either produced there, or produced by a master who has received the skills to make them in one of the weapons centers of this region.
The shape of the end of the scabbard (Chape?), as well as the shape and location of the movable ring tell me about this.
This spherical form chape of the scabbard, archaic for the Ottoman Khanjars, was preserved by the 19th century only on bichaqs from the Bay of Kotor region.
The bichaq itself may be a little older and probably this is not its first scabbard.
The ornament on its handle looks Greek to me, but this ornament is also often present on the handles of knives from the Boka Kotorska.

I agree with you that there are similarities.
The scabbard locket, the suspension ring and the spherical scabbard ending are similar.
There are major diferences too.
The scabbard shape is different and there is no use on niello.
Furthermore the pattern of the scabbard ending looks very turkish to me.
