I'm sorry to say that I am unaware of any photographers from Norway. However, your next-door neighbor, Sweden, has produced a few studios -- "Stan of Sweden," "Sven Swede," and the more well-known (but sadly anonymous) "Foto Grafo." Little is known about any of these photographers, apart from their post office boxes. If there were some physique photographers from Norway, I'd love to find out about them!
(I did have a huge crush on Norway's Gunnar Rosbo back around 1980!)
