I've got a possibly scandinavian brooch with a vikingship and a seadragon.
It is marked 830S EH REG NGF N.
Can anybody locate the origin of this brooch?

Thank you for your help!

8 months later, I've found several sources with information about the hallmarks.
They're told to stand for "NORNE NORWAY", an early workshop (name) of Aksel Holmsen.
Can anybody verify these information?

Regards,
