I posted this on the american forum, but have since been told that this spoon maybe Norweigian. It is 5 1/2" long. The back is marked P.J.P830 S. It is very pliable and would bend easily. If anyone has any ideas please let me know.
Definitely Scandinavian 830/1000 silver, most likely Norwegian, maker will probably be difficult to track down. Most likely dates from late 19th century to well into the early 20th century.
