I inherited a silver spoon from my Grandmother who immigrated from what was then the Austro-Hungarian Empire. It should date to the early 1800's but I am unsure. As the attached picture shows, inscribed on the spoon handle are the letters 'L' and 'M' and 'K'. Next to these letters is a circled 'N' surrounded by numbers (1802 ?). Separately, these is another symbol which is difficult to discern. Can someone help me identify these hallmarks? Thanks.
