Hello all... I have a lovely butterfly pin here. I am not computer or internet savvy, so I am feeling quite accomplished after figuring out tinypic as well as the copy and past thing. Yay! I need help with these hallmarks. I have done some research, and discovered that it may be from the Scandinavian area.
The mark 925S, was a clue that sent me to the Norway, Sweden areas. The middle symbol is the most perplexing for me, as well as the last two marks, NM. I have searches for hours, and days! I could not find anything like this. Please help! Thanks in advance!
