German B1E incendiary

This was the standard German incendiary device of the early war period, a magnesium-alloy body with steel fins. 347 by 50mm and weighs 655 grammes without internal mechanism.

The dark ring aroung the forward body, just behind the nose-cap join line, contains flame-holes to assist the initial ignition.

Once the thermite had ignited the magnesium body it was very difficult to extinguish; ARPs had a shovel on a long handle and a lidded square steel bucket filled with wet sand into which they were to place incendiaries in order to contain them until they had burned themselves out.

I don't know why this one hadn't ignited, perhaps the detonator failed. It was retrieved by by great-uncle John who during WW2 was an air-raid warden at the Shorts factory on Queen's Island; he cycled there from Newtownards each day.
