Thanks Gummipuffer. Last year I was researching a story for family history purposes about my Mum's posting to the Middle East Command in 1941 as a WRAF codes and ciphers operative. It was based on a record compiled by one of her contemporaries which described their Sunderland (or Empire) flying boat journey across Africa from Lagos to Cairo. I did find quite a few Sunderland pics and sufficient technical data for the account but not what I really wanted. This was to identify the the actual flying boat my Mum flew in (departed Lagos 1 Sep 1941), get a picture of it, perhaps the names of its pilots and what eventually happened to it. Bit of a tall order I know!
