Gerben, as promised, I looked further into the subject.
What I ended up with, is finding three articles. In total 15 A4 pages of info and pictures. Everything you would like to know + then some!
It's published by "Scandinavian Ammunition Research association" in their "Bulletin" #79 2002, #81 2002 and #84 2003.
Out of respect for the author's, I don't feel it's right just to copy it directly into the forum. So my problem is what to do now? I have taken pictures of all the pages in the articles, shall I send them to you trough mail?
It's written in Norwegian, so perhaps that Dutch cartridge collector with second home in Norway can help you decipher it?
If you send me his address, I will send some boxes for him to forward to you
