Original Canadian WWII Brodie MkII Steel Helmet by General Steel Wares with Helmet Net – Dated 1941 Original Items

Original Item: Only One Available. This is a very good example of a genuine Canadian -manufactured Mark II steel helmet, dated 1941 on the shell, complete with a brown helmet net. It comes with the correct dark OD green satin paint used on Canadian helmets, which has only some light wear on the stainless steel rim.

The stamping on the underside of the rim reads:

G. S.W.    R

MK I   1941

G.S.W. stands for General Steel Wares and Aluminum Goods of Toronto, who made helmets from 1940 to 1942. While this helmet is stamped with Mk I, that is the designation GSW used for the first shell version of the MkII Helmet, so this is definitely a MkII helmet. The shell is overall in great shape with no major issues. The helmet net is a dark brown color, with nice cotton construction, typical of the type used by British forces during WWII.

The original liner is in very good used condition, with nice oil cloth, and only light wear from service. It does not have any maker markings that we can see on the fiber support bands, but not all makers put their markings on that location. We see no reason to doubt that this is an original WWII Liner. It looks to be about a size 7.

The chin strap is in good condition, and is in the typical light tan color. It is the standard type seen, with springs inside fabric on the end sections, and adjustable middle section.

The marking SG12535 is painted onto the inside of the shell under the brim. We assume this is the operating number of the soldier it was issued to at some point, but we do not know if this was added during WWII or after.

This is a great change to pick up a nice condition WWII Canadian helmet with an original helmet net. Ready to display or even wear!

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.
