Hello, the "N" in a shield is the mark of Hanau maker Neresheimer, the two marks below look like Swedish import marks, as to the upper marks - sorry, no clue. Best wishes, Bahner
It is swedish import marks. Crown and half moon is Germany after 1886. Its funny - mark say 800 silver and swedish standard is 830 as the other mark says. So first mark gave it a lower silver content than it actually had.
looked again at the marks - it has 3 sets of marks. One german halfmoon and crown + 830 + maker. One set of swedish import marks - katfott + s (i.e. silver on imported products) and the it has a third set of marks - the 800 mark + ?? so what country is that (The Netherlands??)
