The photo was possibly taken by the RAF, probably by Cotton's PRU Flight at Heston [near where my grandparents and dad lived at the time] and was intended to show the location visible from the air of the RAOC vehicle park. This was in the former Greyhound track and on nearby land. The directors of High-Duty Alloys Limited compalined to the Air Ministry that because their factory was an essential producer of aircraft alloys, they were likely to be hit by the Luftwaffe when going for the up to 800 vehicles stored nearby. There was discussion in the Archives file about the vehices being obvious to enemy agents as well as German aircraft. The matter went up as far as Churchill but the answer was that the vehicles turned over all the time...in the end it was a fait accomplii and no special efforts were taken to disperse vehicles.

The photo ended up in the Slough Estates archives, and I had a hi-res copy made to CD-Rom.
