My father worked for the British "Ministry of Supply" [UK_MOS].
In the 1950's he used to travel between England and Australia [Edinburgh airfield in South Australia].
As a teenager I asked my father to take some photographs on the way. Unfortunately the camera
was a very small [spy type] Kodak Bantam camera with very small negatives and grainy film.
It is still a unique record of a very different era of travel.
