Carl Zeiss RB 50/30 aerial camera

Franke & Heidecke as civil firm did not have a significant militar production during the WWII, however they were required for some specific work sometimes like to manufacture the Carl Zeiss RB 50/30 aerial photogrammetric camera used on several Luftwaffe aircrafts for aerial reconnaissance, this camera was provided with motors to work automatically, it took 60% overlapped images that could be used sterescopically too. Anyway this camera needed some parts and accesories to work that F&H did not manufacture.-
