Cossack russian , caucasian belt

[BBking]

Good evening dear members,
I saw the post about the caucasian buckle belts ans I wanted to show you this model.

Really nice but I have a basic ''stupid'' question about the way it was used: how do they attach a kindjal on it ?

A string fixes to the kindjal scabbard then passing through some of the small holes ?

There are many stamps on the pieces ,
Really glad if someone can help for maybe fix the origin translate it .

Best wishes
