Athol mentions in one of his letters to his mother that he took some photos whilst travelling as Observer in one of 'A' Flight's machines. None of these images have dates on the reverse. The first two images measure approx. 80mm x 55mm. The final image is larger and has interesting annotations on the reverse.
This appear to be the Kharga Oasis and township. You can se ethe struts from the aeroplane on the top-right of the image.
Another aerial photo.
Athol mentions that they were flying too high for some of the images to make sense.
See letter dated 12 September 1916 (posted yesterday). The pilot was Lt Jones.
This pairing shows the photograph and the annotations on the reverse.
This appears to be the base for 'A' Flight at Sherika.
The annotations on the reverse read (from top and clockwise):
'Tarmac, H.Q., Bath, Officers, Egyptian Cavalry, Hangars.'
It is tricky to make this out as they are written in reverse and you need to read them in a mirror.
Approx 120mm x 90mm.
