Interesting to look at the very old map-oldest i have seen and with secret stamped all over it one assumes wartime.
Interesting to see the rail link from the Reading /Windsor to Waterloo line at Feltham which was never built but probably should have been - even today there is still a lot of open space between that line and southern LHR.
The 'Sludge' works known as Perry Oaks was reduced in size a little and the Duke of Northumberland's canal rerouted parallel to the Longford river along the southern boundary.
Perry Oaks hamlet had to be the least desirable place to live in Britain with runways on either side of it and back in the day another runway immediately to the east with sewage works to the west. Challenge for any estate agent to make that sound good.
All gone now of course under T5
