This is a fridge magnet or toolbox magnet depending where you want to stick it. The roundel is the design used by the RAF between 1942-47 used mainly on the fuselage, with different designs for the wings.
Made from reverse engraving plastic with the four colours painted on the back, it is a reproduction of the fuselage markings on RB396 Hawker Typhoon, the last surviving combat veteran of WWII.
A project to restore the plane to an airworthy state has begun, and it is expected to be airworthy in time for the 80th anniversary of the D Day landings. For further information have a look at www.hawkertyphoon.com.
