I've found a silver riza.It seems very well handworked.
It has two cyrillic inscriptions at the right and left top corners.
It bears three hallmaks. One is similar to the mark of Heidelberg as reported in the book of Jan Divis.
The other one is the number 12 (12 lot I think).
But in the last one, may be the hallmark of the silversmith, I can't recognise nor latin letters nor cyrillic ones.
Maybe someone can give some information about the matter Thanks in advance
