Would you be able to help point me in the right direction of a date lookup chart? I am researching a ring with these marks:
члю appear to be the marks before the assay mark, then л (for L?) before the 583/14K. Further to the left there are 2 marks, very difficult to see, one is a circle, then what looks to be '55'.
4ЛЮ
ЛЮ stands for Leningrad Jewelry factory. Number 4 in front of it is year code for 1974. Mark with the star and fineness for 14K.
In front of the star is letter Л (L) for Leningrad assay office.
