Update: The ring went for auction and today I won it, some other biker dude that just liked skulls ( according to previous auctions he bid on ) bid on this ring. I couldn't help myself, I'd rather have it for its history and not letting it go to some biker.I will post more photos of it once it's in my possession. This could be a german canteen ring that a swedish volunteer bought, then brought back home. I'm not saying it is, but it COULD be a Waffen SS ring if so. Anyway, I'm happy about my bid, paid €113 for it. The swedish interest in collecting ww2 rings is not that popular as in other countries. Let's hope the inside will look good once i'm able to snap some micro photos.
