Hi Olga, Russian Federation after 1994. Example bellow with «П» — Поволжская. Yours is ЗПрикаспийская Республика Дагестан г. Махачкала Two last letters in the mark on the left stand for the maker ``ЗА``. Regards
I suppose you meant ``only letters`` for date and maker`s codes. Everything is explained bellow.Letter codes in the mark on the left and Kokoshnik on the right of your ring.Legislated in Russian Federation since 1994.
Codes before 2000(2001). So, the ring was made in 1997. I think everything is clear now. Btw. Kokoshnik is really the same (possibly only slight variation, but the same).I see no difference. На данном рисунке, представлен шифр года [:9] — 1999 год, [Я] — Восточно-Сибирская инспекция, [Ц] — шифр именника производителя
