rosenthal.com has nothing to do with the former German producer Rosenthal so I assume that you mean another website. Still I have to object as shown mark was NOT used during the war. It’s a pre-war mark which is pretty well known and is fully documented in real expert books, not in the poor excuses of US collector books or sites like this one. What you have there is a “Modell I” which was produced between 1933 and mid-1939.
