The below hand-drawn map of Abingdon details the various Civil Defence depots and centres. The various symbols are used to depict the service in operation at that location.
The small circles with numbers are, I assume, wardens' posts (usually these were denoted by a W with a dot above).
F in square = Fire Station
F in triangle = Not sure but probably fire related
Red cross = First Aid Post
Crossed black flags in circle = Main Report Centre
Black flags = Report Centre
DV = Vehicle Decontamination Depot
S in two circles = General ARP Stores Depot
RS in square = Local Respirator Store
R2 = Rescue Depot (with two rescue squads)
D2 = Decontamination Depot (with two cleansing parties)
Wide cross in box with no top line = Manual Telephone Exchange
Dot in square = Not sure, possible warden related
Not entirely sure what the Action Stations in pencil refer to.
