INERT DEACTIATED. At the start of WW2 with the firebombing of British cities by the German Luftwaffe in the 1940/1 Blitz much information was used from the German method of dropping incendiary bombs followed by high explosive bombs which would spread the fires, injure/kill the firefighters/rescuers and their equipment. The British 4 pound incendiary bomb was developed by ICI in 1934 after various trials including the German incendiary bomb. The design was finalised with a all hexagonal bomb with a magnesium body filled with thermite, a flat steel tip and pressed steel hexagonal fins. This bomb could penetrate the roof and 1 to 2 upper floors of a normal building. This is a rare British 4 pound incendiary bomb with the normal flat bottomed type. The bomb measures 21 inches in length including the pressed steel hexagonal tail fins. The bomb is complete with a pressed steel tail fin assembly including the alloy fuse holder that would have originally screwed onto the rear of the incendiary bomb. The bomb has traces of the original black stencilling to one of the sides including the number A/EB ???? 14262.
