It is a Polish vodka or a kiddush cup with two sets of marks ,old and new marks. The lower set carry the old marks. From left: The maker's mark (SH), unknown to me. The fineness mark 84 zolotniki (875/1000) and Warsaw's town mark , the double headed eagle. The last mark to the right ???? no idea, but my guess would be a trade mark. The mark 84 is an individual mark implemented by the silversmiths in Warsaw on the request of their customers in mid 19th cent. Remember that Poland didn't exist 1795-1918, it was a part of Russia, Prussia and Austro-Hungarian empire.
The upper set of the owl and the woman's head with 2W are the independent Poland's new silver marks from 1920-1963. The owl is called Lombard mark, a mark for pawn or used items. The woman's head is the official Polish control mark for 1920-1963. The figure 2 stands for the fineness of 875/1000 and W for Warsaw.
Let's hope somebody else can identify the maker and the mark to the right (cannot know it all...;-)))
