Above; Bf 110's coded '3U' with underwing 900 ltr drop tanks from 9./ZG 26 (probably 'E's) based on Sicily photographed on a convoy escort sortie in the autumn of 1941 over the Mediterranean. The Staffelwappen can be seen on the nose of the aircraft – a stylised " Hahn" or cock on the double chevron of the Zerstörerverbände.
