I'm hoping someone can clarify conflicting information I've gathered while researching the mark(s) of Wiwen NILSSON. Someone has stated on another silver forum, regarding another piece of jewelry, that they did not think the mark which is the same as on the photo I'm submitting, was used by Wiwen Nilsson because it is not in script. However a research book on sterling silver jewelry states that during his career, Wiwen Nilsson also used a mark in block letters, in addition to his more familiar scripted mark. I can find no other Scandinavian silversmith with the exact same spelling of the name N I L S S O N (except for A. Nilsson, an affiliate of Wiwen Nilsson). This makes me wonder if this is in fact, a mark used by Wiwen Nilsson. I'd like to know the forum's opinion please, or if anyone can provide more information regarding the mark NILSSON in block letters. TIA.
Here are photos:
