Photo showing Werk Süd with IW on the left and F1 on the right taken on 19th August 1943. The photo shows only light damage to the main halls, although F1 was actually hit at least 11 times, and hits to the separate single storey workshops to the right of the IW hall. The long storage (oil and paint?) shed above IW and the woodworking shop at the top of the picture appear undamaged. Anti-aircraft platforms (at least 3) can be seen on the roof of IW but that seem to be empty of guns. F1 shows two AAA platforms (there was at least 3 at this stage and maybe more) and they may have guns installed. General W. Dornberger mentions defensive AA artillery fire from the from the roof of F1 in his 1952 book V2 (1954 in English).
