Sniper / Powar.. I will repost:
"I can only refer to the one 'Norge 1940' ring"

Flea marks, dug, how many years ago,,none are provenance... I will repeat as we do have a large international member ship [ this topic alone we have Americans, a German, Russian, Italian!!, plus whoever is looking in! ] So refering only to the Norge 40 ring,,,it is easy to see it is cast and also engraved recently..

Don't know or have seen the other emblem ring or the Narvic. They could very well be authentic and welcome photos if you would like to post .

Thanks for all posting/responding here.. We are collectors here. Some with much experience,,some with little. Main thing is we look out for ourselves.. Keep on the hunt guys....,G.
