A steel helmet, popularly called a tin hat, is used as protective headwear by military personnel and civil workers in times of emergency and disasters. Steel helmets were first used in World War One, with the Allies troops using a design produced in London by John Brodie in 1915. This helmet was constructed in one piece pressed from a single thick sheet of steel and variants of this design have been used by military personnel ever since. It is not clear whether this particular item comes from World War One or World War Two. This steel helmet is retained as a good example of the protective headwear worn by Australian military personnel in World Wars One or Two.The crown of his helmet or tin hat is of an oval shape and it has a short flattened brim. There are three small holes for the insertion of a chin strap. The hat has some white paint marks and is very rusted.military headgear, history of warrnambool
