It's a known fact F&H as civil firm did not manufacture significant militar equipment during the WWII, but they were required sometimes to do some specific work, the Carl Zeiss Reihenbild-Messkamera RB 50/30 was one of them; this was a reconnaissance aerial camera with photogrammetric purpose. It was mounted on several Luftwaffe aircrafts reconnaissance models, Bf 109 E6 and Focke Wulff 189 A among them, it was a large camera provided with motors for automatic work. It took 60% overlapped frames to do photographic maps or to use them stereoscopically; anyway the camera needed some parts and accesories to work that F&H did not manufacture, in other words the camera leaving the F&H factory was not operative yet. This is an image about the camera: http://itarphotos.blogspot.com/2009/11/carl-zeiss-rb-5030-aerial-camera.html and you can see here (second photograph) the same camera being removed from the Fw 189 A, I notice this is a technical and historical page on the WWII and contains real photographs about German aircrafts from that era: http://www.airrecce.co.uk/WW2/recce_ac/LuftAR2.html Carlos --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
