Thehełm wz. 31 (helmet, 1931 pattern) was the basiccombat helmet of thePolish Army before the outbreak ofWorld War II and during theInvasion of Poland. The helmet became the basic type of combat headgear for Polish military formations in the 1930s and during the early stages ofWorld War II. It was also exported toPersia,Albania andRepublican Spain. By September 1939 approximately 320,000 helmets were delivered to the Polish Army.
While it was not the most common helmet in Polish service during World War II (in 1939 most of the mobilised soldiers were issued old FrenchAdrian helmets), it became somewhat iconic and widely regarded in Poland as one of the symbols of Polish resistance. Because of this, thehełm wz. 67 designed in the late 1960s was based on the wz.31's silhouette.
The wz. 31 was an all-metal one-piece helmet with a distinctive peaked visor and a slight "skirt." It was covered with either plain or Salamandramatte paint. Most helmets were covered with a thick layer oflead tetroxide and then painted with standard all-militarykhaki, with some of them painted grey, greyish green or navy blue (the latter worn by the police). The weight of the complete set with inner lining was approximately 1.3 kg. The helmet could be worn with the visor backwards, which was used by artillery officers for increased visibility and better peripheral vision.[1]
After the end ofWorld War IPoland seized large quantities of helmets from other countries formerly occupying its territory. Among the most widely used was the German M1918 helmet, better known as theStahlhelm. Large numbers of FrenchAdrian helmets were also being used. However, as the shape of the helmet was one of the most distinctive marks on the battlefield, already in 1919 thePolish Army started working on a genuine Polish helmet, distinct from those used by the armies of surrounding countries and offering better protection than the German helmet.

The initial work on a new helmet was directed by the IBMU institute in Warsaw, with the chief engineer beingLeonard Krauze. The design team created an outer shell, but the design process came to a halt in mid-1920s due to problems with the inner lining and production process preparation. It was decided to purchase a ready-made design or use a technological process developed in another country.SwedishEskilstuna Stal Pressing ABsteel mill was chosen as the contractor and a Polish commission spent several weeks observing the Swedish technology. In the end the Polish ministry of military affairs decided to buy a license for Swedish helmet suspension and liners, and to design a custom outer shell.
The shell was based on an earlier Polish design, thehełm wz. 30 which never entered serial production. The most notable modification included liquidation of the horn-like ventilator lugs, similar to the ones found on early German helmets. 300 copies of the modernised design were ordered for testing and were then extensively modified by thePokój steel mill, the Warsaw-based Arms Factory No. 2 and theWolbrom-basedIdeal works. Simultaneously, the Warsaw-based "W. Karpiński and M. Leppert" factory designed a new type of grainy non-glossy paint to eliminate light reflection. The new paint was patented under the name of "Salamandra" (salamander) and accepted by the ministry.[2]
The tests of the modernised 1930 design were successful and by September 1932 the first 120 copies were made by the Bismarck and Silesia steel mills, the latter equipped with a complete production line of German World War IStahlhelm helmets. Further tests at the Infantry Training Centre inRembertów near Warsaw led to further minor modifications. Finally the Ministry chose two steel mills as contractors for serial production. TheKielce-basedHuta Ludwików factory started serial production of helmet shells from a nickel-chrome-molybdenumsteelalloy provided by the Baildon Steel Mill. At the same time some of the helmets were being produced from less durablemanganese steel. Due to project's secrecy it was officially referred to in military purchase orders as "kettle production". Initially costing 21,70złoty apiece, with time the price dropped to 16,50 złoty.[3]
Thewz. 67 helmet produced in the times of thePolish People's Republic referred in its shape to the pre-war wz. 31, initially it was even supposed to be painted with anti-reflective "Salamandra" varnish, but this idea was abandoned.
The first batches of serially-produced helmets entered field service in January 1933. Initially issued to infantry and artillery, in time it was also provided to thePolish Navy andBorder Protection Corps.[4] TheBorder Guards andState Police were provided with a variant of the wz.31 helmet with a large (10 centimetres in diameter)White Eagle adorning the forehead. However, at the end of the 1930s it was determined that the standard Polish wz. 31 helmet was unsuitable fortank troops and motorized units; while offering decent protection, it was too large and heavy. Because of that most of motorised units continued to use GermanStahlhelms, while the cavalry used the FrenchAdrian Helmet. The latter was also issued to many of the units mobilised in 1939.
After theconquest of Poland in 1939, the Germans passed some of the captured Polish wz. 31 helmets to theirLuftschutz (civilian anti-aircraft defense) units and sent 1,000 pieces toFinland (Winter War).Red Army soldiers also occasionally used captured Polish helmets. It is estimated that about 200,000 wz. 31 helmets ended up in foreign hands.
During theoccupation, many partisans of thePolish underground used wz. 31 helmets in addition to captured GermanStahlhelm helmets. This is particularly visible during theWarsaw Uprising in 1944.[5]
After World War II, due to the shortage of SovietSSch-40 helmets in thePolish People's Army, it was decided to include surviving pre-war wz. 31 helmets in the equipment. The helmets were modified, equipped with new and often different facings fastened with additional rivets and using a new smooth paint job. The helmet created in this way was adopted as wz. 31/50, using mainly pre-war wz. 31 examples or unfinished shells found in significant quantities in the storage field of the"Ludwików" Steelworks. Most of these helmets did not have the technical inspection rivet characteristic of wz. 31.[6]
The wz. 31/50 helmets were painted smoothly in khaki (for the army) or blue forcivil defense.[7] The wz. 31/50 helmets were also occasionally used in the equipment of various Polish paramilitary organizations. Based on wz. 31/50, a helmet intended for fire brigades equipped with a comb was also created.
The export variants were identical to the original wz. 31 helmet except for the paint: instead of standardkhaki used in Poland the Spanish Republic used black mat.
While the production of the wz.31 ended with the German and Soviet occupation of Poland in 1939, the Kielce-based Huta Ludwików retained large numbers of original helmet shells in its warehouses. After the war production did not resume and instead the Polish Army was equipped with SovietSsch-40 helmets. However, the remaining wz.31 shells were fitted with lining fromGerman M1935 orwz. 50 helmet and issued to various military colleges, paramilitary organizations and civil defense.[8]
