Hi, and welcome to the Forum...............!

It is a US 'Brodie' or 'Brody' of the First World War.

Helmet M-1917

the US M1917

When the British Mk. I was selected by the United States Army, its United States production version was designated and standardized as the Helmet, M-1917. Until United States production of the M-1917 could begin, the United States Army purchased the 400,000 available British Mk. I helmets in England and issued them to the American Expeditionary Forces already in Europe. Production was begun on the M-1917 helmets in the fall of 1917. By the end of November 1917, large quantities of M-1917 helmets became available for the United States Army.
