Help identifying silver mark on kindjal

[motan]

I knew I could trust this forum members for some good answers. Thank you. Here are some additional pictures. Unfortunately, the blade is severely damaged by rust and I can only stabilize it. It is a thin and sharp, with a diamond cross-section and looks fairly well made. Remains of leather or similar material once covering the sheath are visible in picture.
About the small size later. I have participated in previous a thread on the subject and it is an interesting subject.
