Interestingly, a selection of these images were used in a book entitled ‘Pictorial History Of The Fleet Air Arm’ by John D.R. Rawlings (Ian Allan, 1973) and credited to Capt P.C.S. Chilton.
The one showing the two Martlets in front of the Farman has been cropped somewhat on the modern Flickr account–the version in the book has another Martlet off to the left.
Still very good stuff though.
