Also known as: ブロディヘルメット
A Combat Helmet designed and patented in London in 1915 by Latvian inventor John Leopold Brodie. It is also known as the battle bowler, Tommy helmet or doughboy helmet. It was used by British and Commonwealth forces from World War I until the end of World War II.
It looks similar in design to medieval kettle helmets, due to its domed top and wide brim.
