I can only refer to the one 'Norge 1940' ring: Same question to you friend,,why is it from the period?

A Norge 1940 ring like that was auctioned beginning of Oct... Then another was offered for auction a week ago. One had engraving in the band the other didn't...

You don't have to be a expert to see the ring was engraved recently.. Also it is a cast ring... The ring was made after 1945..

All my message is,,,that Norwegian flag emblem was available to buy a short while ago and could very well still be available to purchase.. A warning for collectors that's all.
