Scandinavian Retro Font Id help required

Sorry that it's such a tiny sample. It is from a Swedish firm and shows the key outstanding letters A, S and G. I can not, despite a serious search find a matching font.
I throw it open to the far brighter minds of typohile. Many Thanks.

Do they have a web site, or some place to see more letters? The image is too small and faint.

No Mike, thanks for looking but that's the only sample I have.
