Here is information about the map for Barnet Common:
This double-sided map covers the southern part of Chipping Barnet. A small portion of the High Street is in the NE corner of the main map and coverage includes Barnet Workhouse, Bells Hill and the southern fringe of the village. Cover then extends southward beyond Ducks Island to Dollis Brook, and westward along May's Lane to Totteridgevale Farm and Whitings Hill. Much of this area is referred to as Barnet Common. On the reverse we include half of Sheet 6.06 and this extends coverage westward to the village of Arkley, including St Peter's church, Arkley Hall and Rowley Green; then further west to Barnet Gate and Hyver Hall.
The map links up with Middlesex Sheets 6.03 Barnet & Hadley to the north, 6.08 New Barnet to the east, and Sheets 6.10 Highwood Hill and 6.11 Totteridge to the south.
