With the end of World War I, the countries that were involved in it had already incorporated the steel helmet as another element for their armies. Spain, by remaining neutral during the war, still took a few years to regulate the steel helmet for the use of the army. 

​

It was not until 1930 that the 1926 model helmet was declared as regulatory for the use of the army. Designed by Artillery Lieutenant Colonel Antonio Ramírez Arellano, it was manufactured at the Trubia National Artillery Arsenal (Oviedo). 

​

The design of this helmet is reminiscent of the German M16, with side and rear protection visors, but unlike the German model, the "birth" of the wing is not marked on the M26.

 

The interior trim is made up of three double tabs, initially made of black leather and attached to the helmet by 6 rivets. The chinstrap was attached directly to the helmet by 2 aluminum rivets with holes for ventilation.

​

The helmet had acceptable ballistic characteristics, but with a major problem due to poor ventilation. The helmet was delivered in a gray-cement color, even during the Civil WaryesThey used to repaint khaki or brown.

​

At the end of the Civil War, all possible helmets were recovered to repaint them green and change the trims, and later in 1943 a frontal loop for the army emblem was added.

​

The model of the collection is painted brown. Black leather interior, it can be seen that the rivets that hold the chinstrap are flat without holes. It does not have the characteristic frontal loop of the helmets recovered and used after the War.
