Here are the details of maps for Heathrow:
This detailed map covers an area where, remarkably, scarcely a single feature remains traceable today. Author Tony Painter notes that in 1934 the picture, with its farmsteads, had changed little since the Middle Ages, but by 1936 plans were afoot to develop a civil airfield on the Fairey site nearby. Heathrow Airport was duly opened in 1946 "with limited and primitive facilities". Features on our map include Heathrow Farm, Perrott's Farm, Cain's Farm, Heathrow Hall, Perry Oaks and some orchards. On the reverse we include part of adjacent sheet 19.07, covering Perry Oaks Sludge Disposal Works, part of the area now being used for Terminal 5. A directory of the hamlet of Heathrow is included, with just 9 entries.
The map links up with Middlesex Sheets 19.04 Sipson to the north, 19.12 East Bedfont to the south and 20.05 Hatton to the east.
