again, MAJOR thanks for your educated answers.
I just wanted to be sure I got it right :
1. when you write
Д is badly damaged or deliberately erased (not uncommon in Soviet Russia).
you means that it was hallmarked that there IS a problem with the ring? Are you assuming that it was re-hallmarked in the soviet era?
2.
The ring was remarked after 1927 with 583 for 14 ct,
- you means that it was made between 1927 - 1958?
3. I was wondering what is the small trigle on the far left in the 583 hallmark.
4. is it common that one hallmark out of 4 will be upside down?
Thanks alot :-)
