Henry Crun,
Here is another shot of TE400 that I picked up on ebay quite recently. You may have even taken it. Note prop position, rudder, elevator, concrete, grass, shadows etc, all look like the the same place at the same time.
There is nothing written on the back save for some filing reference in pencil 87/197 and a ringed 92.
I would ask does it still look like Woodvale in 1957 from this angle/geography?
I ask because TE400 became 7240M and although incorrectly marked 'M7240', and not the first, here is a shot by M P Marsh dated 1956 and thought to be the gate at RAF Honiley.
Regards,
PeterA
ps TE400/7240M is no longer with us and it must be assumed scrapped some time in the mid to late 1950's.
