I am puzzled by this berry spoon. It has very unclear marks and it might not even be silver, although it looks and feels like silver to me. The first mark looks like KP but I can't find any such maker. The last one seems to read NS or N&S but I can't be sure. The middle one is completely unreadable. I can't see any lion passant or town mark, unless the middle one is one of those.
Someone has scratched a series of letters under the marks. It could be a UK postcode - but why would anyone deface an old piece of silver like this?
And if it isn't silver, why bother with this identification? The spoon is 195mm long. If anyone could hazard a guess to the age or maker, or even if it is silver, I would be very grateful.
