I'll admit that I've only scratched the surface on info on Swedish steel but the following sites might yield some insight:

http://en.wikipedia.org/wiki/Western_use_of_the_Swastika_in_the_early_20th_century#Sweden

http://en.wikipedia.org/wiki/ASEA

By the way it looks like the English are to blame for the use or coining the ole Swastika.

Kind Regards,
