RAF Operations Room Counters
Very Rare Original RAF Plotting Room Counters and marker.
Used for plotting an enemy raid on the Operations Room map table.
There were three types of counter and colours (see last photo for the explanation of this).
The counter colours correspond with those on the RAF Sector Clock.
Counter size is approximately 2.5 cm, and they are made from an early form of celluloid plastic.
There are three counters and one 'Hostile' marker letter plus a wartime RAF map of the strait of Dover.
The counters, marker and map are in an excellent condition if a little soiled.
