So I think is Scandinavian because I found it there... but I can be totally wrong, there are 900 writting in both sides (?!) of the markers mark which is a stylized S H in a oval. The total length of the hallmark is about 1 cm. Sorry that the image is not so clear, I might be able to make a better photo with natural light so we can see it better.
I am a beginner, and lots to learn, but I hope this post gives some light on this topic and someone else can get something out of it! Hopefully one day I will be able to help myself with Scandinavian silver identification as well!
