Original WWI Portuguese M1915 Corrugated Steel Helmet, from the 6th Infantry Brigade, Portuguese Expeditionary Corps.

Original Item: Only One Available. This is a nice example of a WWI issue M1915 Portuguese corrugated steel helmet. The M1915 helmet was the primary combat helmet used by the Armed Forces of Portugal during the WWI era, and was not replaced until the 1930s, when the British Brodie based Mk1 helmet was adopted.

The M1915 was a lightweight helmet designed by British Major J. MacIntosh and produced in Birmingham, England. The corrugated bowl design was possibly to deflect bullets or to increase the strength of the shell, but the exact motivation is unclear. Unfortunately, these helmets proved ineffective in the trenches and the British sold large quantities to Portugal. These were originally painted a gray-blue color, but these helmets often were repainted green for service in the post-war years, as this example has been. There is also a unit marking on the front of the helmet, 6th Infantry.

The helmet is in good condition, with the expected wear from service and age.  The leather liner is missing. The felt top is missing.

A hard-to-find helmet from the WWI era, original paint.
