These folks started in business about 1940 .
Right now , they export directly to Denmark , Finland , Germany , Sweden & the U.S.
They sell a bunch of products in Norway too .
It's a well-recognized brand , and perhaps contacting the company will get you info "from the horses' mouth" about the exact piece you're checking out .
Then again , a forum member here might just have the same thing @ the tip of their fingers ...
