Helmets are one of the easiest ways to date a piece of kit at a glance, and one of the most collected categories we deal in. Every major shift in helmet design followed a shift in the way wars were being fought — shrapnel in the trenches, shaped charges and IEDs a century later. Here's a trade-eye run through what changed, why, and what's actually worth having in a collection.
WW1: the Brodie and Adrian set the template
Before 1915 nobody wore a steel helmet into the trenches — soft caps were standard and head wounds from shrapnel were brutal. The British Brodie helmet arrived in 1915: a shallow, wide-brimmed steel dish designed mainly to stop shrapnel falling from above rather than direct hits. It was cheap to press out of a single sheet of manganese steel, which is exactly why the Americans adopted a near-identical version (the M1917) when they entered the war.
The French went a different route with the Adrian helmet, a lighter, more tailored design with a comb ridge down the top and a small frontal badge denoting the regiment. It offered less coverage than the Brodie but was more comfortable for extended wear. The Germans, meanwhile, introduced the Stahlhelm in 1916 — deeper sides, a distinctive flared skirt at the back of the neck, and lugs on the sides originally meant for a bolt-on armour plate. The Stahlhelm silhouette is arguably the most recognisable helmet shape in military history and it stayed in German service, in updated forms, all the way to 1945.
WW2: refinement, not revolution
By the time WW2 broke out, most of the WW1 designs had simply been improved rather than replaced. The Stahlhelm M35/M40/M42 tightened up the manufacturing process. Britain moved to the Mk II, a modest update on the Brodie shape with a better liner and chinstrap. The real leap came from the Americans with the M1 helmet in 1941 — a two-part system pairing a steel outer shell with a separate fibre liner that could be adjusted for fit. That two-piece idea was ahead of its time and the M1 stayed in frontline US service, largely unchanged, until the late 1980s. We still see genuine US GI helmets with the original liner come through fairly often, and they're a solid, honestly priced entry point if you want a real WW2-pattern piece rather than a reproduction.
Cold War: NATO standardises, the Soviets go their own way
Through the 1950s to the 1980s helmet shapes settled into two camps. NATO countries mostly kept riffing on the M1/Brodie family — Britain's Mk4 "turtle" helmet is a good example, deeper and rounder than the wartime Mk II, and still turns up regularly in Mk4 helmet net and scrim setups for anyone building a period-correct Cold War loadout. On the other side, the Soviet bloc ran with the SSh-40 and later the SSh-68, a simpler pressed-steel design with a distinctive three-pad suspension liner rather than a separate fibre shell. We stock genuine Russian Soviet tank helmets and general-issue Warsaw Pact pattern helmets, both popular with collectors putting together an Eastern Bloc display.
The Kevlar era: PASGT to modern cut helmets
Everything changed again in the early 1980s with the American PASGT helmet — the first widely issued helmet made from Kevlar rather than steel. It looked almost identical in silhouette to the German Stahlhelm (soldiers nicknamed it the "Fritz" helmet for exactly that reason) but the material was a genuine step change: ballistic aramid fibre that stopped fragmentation far better than steel while weighing about the same. Britain followed with its own Kevlar design, the Mk6, issued from 1985 and still the pattern most people picture when they think "British Army helmet" today. We carry genuine British Army issue Mk6 Kevlar helmets, along with matching DPM camo covers for anyone finishing a period-correct set. Britain has since moved on to the Virtus helmet system, but Mk6 stock is where most collectors and re-enactors start.
Beyond the battlefield: pith helmets and parade kit
Not every helmet in the catalogue was designed to stop shrapnel. The pith helmet has nothing to do with ballistic protection at all — it's a colonial-era sun helmet, built from lightweight pith or cork and covered in cloth, designed purely to keep the sun off during service in hot climates. Both the British and French pith patterns are still popular for historical displays, colonial-period re-enactment, and even themed events, since they're comfortable, genuinely wearable, and instantly recognisable.
What to actually look for if you're buying
A few things we always tell customers before they buy a helmet as a collector's piece rather than just a costume item:
- Liner condition matters more than shell condition. A dented shell is honest wear; a missing or rotten liner is a real problem, especially on M1 and Mk6 patterns where the liner is a separate, harder-to-source part.
- Chinstraps are consumables. Most genuine surplus helmets we see have had the original chinstrap perish or go missing entirely — factor in a replacement rather than treating a missing strap as a dealbreaker.
- Rank and unit patches are a separate market. If you want to dress a helmet correctly for a specific unit, patches and badges — like our Lance Corporal helmet patch — are sold separately from the helmet itself, so check what you're actually getting before you buy.
- "Genuine issue" and "reproduction" are not the same thing. Ask which you're buying. Genuine ex-military helmets carry service wear, sometimes soldiers' own markings inside the liner, which is part of the appeal for serious collectors.
Wrapping up
A century of helmet design boils down to three real turning points: the move to steel in 1915, the two-piece shell-and-liner system pioneered by the M1 in 1941, and the switch to Kevlar with the PASGT and Mk6 in the 1980s. Everything else is refinement around those three ideas. Whether you're after a display piece, a re-enactment-ready Mk6, or a genuine Cold War Soviet helmet, knowing which era a design belongs to makes it a lot easier to buy the right one.
