Here are the details of maps for Orpington:
It was only in the 1920s that Orpington was transformed from a quiet Kentish village into a London suburb, says author Pamela Taylor, and this map captures it in its early rural existence. The southern part of the map has the village centre, with All Saints church, the British School, White Hart inn, remains of an old priory, Broomhill Common, and a few good sized houses near the crossroads. The main (unnamed) road runs in a NE direction across the map to New Town, near Northfield, where we find three planned streets. Nearby is the Corn Mill. Eastward the map extends down country lanes to houses called Ramsden and Petting Grove. On the reverse are directories for Orpington in 1869 and 1875.
