NEC SOLI CEDIT
sehr fesch. So eine schraege Muetzenhaltung war strengstens untersagt! Weiber!
By the way, the above photo is flipped. (Either that, or she wore a man's coat and the Reichspost patch on the wrong sleeve.)
I am not even convinced that she's German, as a matter of fact. The cap eagle does not appear to have the outlines of any of the German national eagle designs, the overall cut of the uniform is not typical for German female uniforms either and that elaborate sleevepatch doesn't ring any bells at all.
My gut feeling is Norwegian.
