Original British WWII MkII Brodie Steel Helmet with Dual Color Helmet Net – Dated 1939 Original Items

J S S stands for manufacturer Joseph Sankey & Sons, who made Brodie helmets from 1938 to 41. M H May be the steel supplier or the heat lot number. 1939 is also stamped on both of the chin strap attachment bales. Being an early production helmet for WWII, this helmet has the more complex Mk I liner, which is marked on one of the support straps:

History of the Brodie helmet:
The Brodie helmet, called Helmet, steel, Mark I helmet in Britain and the M1917 Helmet in the U.S., is a steel combat helmet designed and patented in 1915 by Englishman John Leopold Brodie. Colloquially, it was called the shrapnel helmet, Tommy helmet, Tin Hat, and in the United States the doughboy helmet. Worn by Australians during WW2 and sometimes known as ‘Panic Hat’. It was also known as the dishpan hat, tin pan hat, washbasin, battle bowler (when worn by officers), and Kelly helmet. The US version, the M1917, was copied from the British Mk 1 steel helmet of 1916. The German Army called it the Salatschüssel (salad bowl).

At about the same time, the British War Office had seen a similar need for steel helmets. The War Office Invention Department was ordered to evaluate the French design. They decided that it was not strong enough and too complex to be swiftly manufactured. British industry was not geared up to an all-out effort of war production in the early days of World War I, which also led to the shell shortage of 1915.

A design patented in 1915 by John L. Brodie of London offered advantages over the French design. It was constructed in one piece that could be pressed from a single thick sheet of steel, giving it added strength.

Brodie’s design resembled the medieval infantry kettle hat or chapel-de-fer, unlike the German Stahlhelm, which resembled the medieval sallet. The Brodie had a shallow circular crown with a wide brim around the edge, a leather liner and a leather chinstrap. The helmet’s “soup bowl” shape was designed to protect the wearer’s head and shoulders from Shrapnel shell projectiles bursting from above the trenches. The design allowed the use of relatively thick steel that could be formed in a single pressing while maintaining the helmet’s thickness. This made it more resistant to projectiles but it offered less protection to the lower head and neck than other helmets.

The original design (Type A) was made of mild steel with a brim 1.5-2 inches (38–51 mm) wide. The Type A was in production for just a few weeks before the specification was changed and the Type B was introduced in October 1915. The specification was altered at the suggestion of Sir Robert Hadfield to a harder steel with 12% manganese content, which became known as “Hadfield’s steel”, which was virtually impervious to shrapnel balls hitting from above. Ballistically this increased protection for the wearer by 10 percent. It could withstand a .45 caliber pistol bullet traveling at 600 feet (180 m) per second fired at a distance of 10 feet (3.0 m). It also had a narrower brim and a more domed crown.

The original paint scheme, suggested by Brodie, was a mottled light green, blue, and orange camouflage but they were also painted in green or blue-grey. That same month the first delivery of the helmets was made to British Army troops. Initially, there were far from enough helmets to equip every man, so they were designated as “trench stores”, to be kept in the front line and used by each unit that occupied the sector. It was not until the summer of 1916, when the first one million helmets had been produced, that they could be generally issued.

The Brodie helmet reduced casualties but was criticized by General Herbert Plumer on the grounds that it was too shallow and too light-reflective, its rim was too sharp, and its lining was too slippery. These criticisms were addressed in the Mark I model helmet of 1916, which had a separate folded rim, a two-part liner and matte khaki paint finished with sand, sawdust, or crushed cork to give a dull, non-reflective appearance. In 1917, the liner was modified to include a rubber cushion to make it more comfortable, although this was not adopted for the M1917. Towards the end of the war, helmets were often painted with unit insignia. These are often called “parade helmets” by collectors.
