This is silver dinner fork (Fiddle and thread pattern) which feels like 830 silver or the likes but has no other markings other than 'S & BIH' or 'BIH & S' depending on which way round it looks. From where it came from it could be Finnish but possibly Russian or Baltic. I'm hoping somebody can help identify it.
It does have I.M.C on the front and the same markings were found on a Russian silver spoon.
and wondered if such a piece was originally from a government department, military or naval mess, or consular silver. Do the IMC letters ring any bells with anyone in relation to the above?
