Older ariel pics - 20th Dec 2011 3:18pm
I found this on a motorcycle forum. Looks useful although I have not had a full look at it yet
http://www2.getmapping.com/Products...
it shows aerial pictures from circa 1999 and how it looked in the 1940's
On the right hand side enter your post code (or anywhere you want to view)when the map comes up click on the tab on the top left of the map for 1940 - 47 to see what it looked like back then you may need to zoom out (size blocks just above the pic) to get it to work
you can also drag the view box about to see a wider area than your initial search area
Oh you don't have to pay for preview maps, just if you want to save them
