Hi Chris
I stumbled across this thread while researching the pilot of a Focke Wulf Condor, which claimed the sinking of a ship on the same date and in the same area as the Staffordshire was attacked on 28 March 1941. There is an image in the photo album belonging to 'my' man, showing a ship under attack and captioned with the aircraft crew names. I am no expert on ships but it looks to me like it could be the Staffordshire. The crew of the aircraft were: Commander Lieutenant Robert Maly, Pilot Oberfeldwebel Karl Gendner, Radio Operator Wiedmann, Radio Operator ? (illegible), Flight Engineer Gollon. The aircraft belonged to 3. Staffel of KG 40.
Best wishes
