Viking ship necklace 925s need maker

[Recycle]

I have done my best to research this necklace. I believe it's old. I can read the 925s but not the mark on the left..when I move it around, I want to believe the last letter is an M but it's really worn. I'm hoping someone can identify it by style? I'm guessing it's scandanavian. Any help is appreciated.

Appears to be Norway or Denmark. They both commonly used 925S and 830S. I also make out the letter N not M, but you can see better then me.

I have the matching pin. I knew who the maker was but now when I try to look at the mark I can't read it! lol
If I remember who it was I'll post again. It is Scandinavian for sure.

In case anyone is still interested, I have this pendant and mine is definitely COF for Carl Ove Frydensberg. I wonder if someone else copied the design.
