I am hoping that Postnikov or other Russian expert can tell me who the maker is of this pre-1896 St Petersburg stick-pin.
I have not been able to find an image of a maker's mark of cyrillic KB to compare with, although I have seen reference to a Karl Bok, so that could be a possibility.
There are also some marks on the shank but they are very worn from use.
Can you help please?
