Leica CLA'd body. Shutter lubricated and adjusted and rangefinder adjusted. Wartime Red curtain. Factory verified information: 18.7.1941 sold to Berlin
Shortly after World War II started, Leitz found itself in a sort of a predicament. The foreign shipments of shutter cloth material had seized due to the outbreak of the war. All that was left in stock was an experimental shutter cloth, which had different rubber layering and was red in color. Cameras that were ordered by the German Army, Navy and Air Force had to be delivered to Berlin, they were part of the war effort that German companies had to make.
Leitz decided to use the red shutter curtain material, even though there were doubts on its durability. And over time it became clear that the shutter cloth indeed gave in, the rubber started to desintegrate and left sticky black spots of goo on the shutter.
As a result, wartime cameras with red shutter curtains are pretty rare nowadays.
