I know it's an old thread, but I will agree with Marshall: Meybauer EK2s are marked for silver content only, and even then the marks (I believe) started only after the war. I think award-type Meybauer EK2s tend to be unmarked, even for silver, as were many (most?) award-type EK2s: silver, but not marked as such.
Thank you, Trevor. I feel very fortunate to have been offered this by you.
