Russian ring, kokoshnik hallmark and cirilic letters.

Hello everyone, I bought a ring and have some interesting marks that I can't find the
precedence and the year it have been made. Please if anyone have some knowledge
about it I will be glad if you can help me.
I'm new here and the topics are really awesome.
