Thread:User talk:CodeCat/Gender switch between West and North Germanic

I was just looking at regna- (in Torp), and it seems to be (only) masculine in West Germanic languages and (only) neuter in Gothic and Old Norse. I seem to have run into a lot of the same (masculine in W.Gmc., neuter in ON.), although I can’t remember them at the moment. Is this a well known development? Presumably, most of these words had a single form and gender in (early) Proto-Germanic; can this be reconstructed? I do dislike having a lot of splits for basic words, as it simply doesn’t seem plausible.
