I acquired this Cloisonne Enamel Silver box recently, it was described as Norwegian c1960's. There is no S after the purity 925 mark just the maker's mark EB. I purchased it because I really liked it however I am woefully ignorant about Silver items so I am hoping someone here could please help me. Is it Norwegian? Thank you very much.
