Henckels 900 silver flatware hallmark

Hello, we are giving a set of antique Henckels flatware to our newly wed grandson & his wife and would like to give them some information about the set. I am attaching the Hallmark that appears on all the pieces. My wife thinks she had purchased the set when she lived in Argentina in the 60’s.
Sincerely, Myron Tupa

These are German: 900/1000 standard silver with the normal crescent moon and crown mark used since 1886. We also see the maker’s mark of Koch & Bergfeld of Bremen. Dating this set is not possible.


Thank you very much for your information.
