Not sure about Norway, but I have an aunt in Denmark and she can't follow Danish knitting patterns as they hold their needles differently to her (English) so the directions are confusing - maybe it's just continental???
I found a few more samples of them and they all say they're from a pattern from Dansk Mohair but they were also all made in 2005. So it's possible that company is no longer in business. You could try emailing them and asking.
