I inherited this spoon about 4 years ago, and stumbled upon it yesterday. I have been able to find some info on it from this site via markings (country of origin,silver standard, date stamp), but I would appreciate any other information available. A picture of the box is included also. Thanks for looking!

P.S.- Here are the stamps, in case you cannot see them:
COP ; (unknown- looks like an "S" or a "5") ; O9 (date stamp) ; Nat'l. mark (Swedish, unless I'm mistaken) ; silver proof.
