Pictured below are three seemingly identical Spanish helmets; the model 42/79, the German manufactured M. 35, and the "modello Z".
The M.42/79 is essentially a rehash of that which has gone before (the model Z) with a more highly engineered suspension and chinstrap system.
Its handsome looks still draw from its ancestor the German M.35 which saw Spanish service following the Civil War and accompanied Spanish troops as they assisted the Nazis in their campaign against the Soviets.
Like the "modello Z", the M.42/79 is made of much lighter, thinner steel than its German forebear.
The liner, though much improved from earlier versions, is still an overly-complex design that provides little of the critical space between the shell of the helmet and the head of the wearer.
Comprised of a leather band, riveted to the shell, the liner is a series of fabric and leather straps radiating toward a hammock-style apex.
The finish on this particular helmet is much finer than on other examples. The lack of those typical multiple layers of slopped-on paint lead me to believe that his helmet was in service only a short time.
Spanish police also used the M.42/79 for many years, eventually making the transition to composite helmets:
