If this were English, I'd have no hesitation in calliing it a toddy ladle, but I'm not sure of it's popularity in Sweden.
Anyway, it's 15cm long and has four marks:
One is, I believe, the Swedish three crowns.
An S in a hexagon.
Gohr
830S
I can supply a little.
The 3 crowns is called katfott. Katfott is swedish for "cats paw" due to the similarity.
Katfott is followed by an S if its silver (today).
And for COHR a very large producer of danish silver and silver plate
I dont know what it is used for. 15 cm you say. I have one 20 cm it is for sauce.
I also have one for punch it is 35 cm.
The 2 that I have are more "clean" at the cup - not all the ????
I went through some old undated (about or before 1900 ??) Cohr photos today, and found one showing this ladle next to a tea strainer with the same kind of handle.
