Incredibly rare Operations room equipment used to display important information relating to an enemy raid. When details of aircraft were received at Group Filter room level it was interpreted on a map table using plotting raid blocks and 'counters'. This superb articulated plotting piece are manufactured from four strips of metal, riveted together such that they can be angled to display the route being taken by allied or axis aircraft. The green base paint is typical of that used on wartime airframes. It also has small 'holders' soldered on to allow information cards to be attached appertaining to the aircraft type etc. Approximately 15cm long closed, opening to a maximum of 52cm when extended. Very minor paint loss but in excellent overall condition. A fantastic opportunity to create an Operations room display. NB, map and other items are shown for display purposes only. Stock code M24257.
