RAF operations room plotting table Raid Block.

Scarce 3-Tier Raid Block, as used in RAF filter and Sector Operations Rooms during the Battle of Britain and beyond to display important information relating to an enemy raid. Using coloured arrows, discs and shields a raid was plotted onto a sector map. The raid block was normally positioned at the head of the plotting path of a raid and provided additional information such as strength, height and whether the aircraft were ' hostile ', ' friendly ' or ' unknown '. Other information could be added to the block in the form of plotting pieces on metal stems. This example comes with various tiles and stems to provide this information.
