No One like Kriegsmarine here? I will try to add as much input into this as possible, and would greatly appreciate anyone else to throw there two cents in. The Gilt Metal rank insignia is for a Flugmeldeamt {Aircraft warning service} The bottom sleeve insignia is for Rangefinder operator with NCO schooling. I will quote this out of Brian Davis's Book German Uniforms of the third Reich 1933-1945 The Uniform Jacket was unique to the German Navy. It was worn both as part of the service dress and as a summer walking out uniform, when it was worn over either the blue or white jumper with the blue collar warn outside the jacket. As it was an elaborate Item of dress which served no practical function it was one of the naval garments that ceased to be issued at the outbreak of war and only those persons who already possessed the jacket could continue to use it within the prescribed circumstances. Now all I need is a nice brass Kriegsmarine Buckle and to learn how to tie the Jumper Correctly. Thanks Dan
