General information

The most used and easily recognised bomb of the 2nd world war has to be the German Incendiary bomb, dropped on the UK in their millions , with lots failing to ignite.
It was said to me that during the war , most school boys had the fins of these bombs on their desks , and used them as pencil holders.
One of the first bombs to be mass produced and used in the Spanish civil war of 1936.
Dimensions of 1kg and 1.3 Kg bombs
Oa 13.75 inches
dia 2 inches
tail length 4 3/4 inches

Component parts of the 1KG

1.3 Kg Incendiary the nose was replaced with steel to assist in breaking of tiles prior to igniting.

1.3 Kg with Explosive tail the idea was to scatter the burning magnesium over a wide area.

The 2.2 Kg explosive nose incendiary this consisted of a normal incendiary but added to this was a explosive cylinder which acted as a deterrent for those trying to put out the bomb and of course to do as much damage as possible

sometime ago I was asked if a recently purchased German incendiary bomb was empty or not as the owner could not unscrew the nose fuze ,
These are the weights I obtained from my examples

1 Kg standard incendiary all weights in Lbs

Empty AZ83128* nose fuze no striker etc 1.437 Lbs

AZ8312@ nose fuze with striker etc 1.503 Lbs

Complete with Empty charge case inside 1.598 lbs

1.3 Kg Steel nose fuze AZ8313 no components in fuze 2.235 Lbs

Remember there maybe slight variations but only minor anything much heavier then caution is required !
