Unusual plaque believed to have been used in RAF Filter and Sector Operations Rooms during the Battle of Britain and beyond to display important information relating to the strength of an enemy raid. This relatively crude triangular shaped tin plaque measures approximately 27 x 50mm, is black, with the number '3' hand-painted in white on one side. It came in with other similar plaques and operations room pieces. A fantastic opportunity to create a small operations room display. Some corrosion. Stock code M25708.
