There are a few of these type of ancient Greek helmets at the Metropolitan Museum in NYC, and what always strikes me about them is their size. The ones I've seen could not be worn these days by anyone over ten years old, and even then it would be a tight fit, especially if they wore any type of padding underneath. It gives you a whole new perspective when you consider that the man-killing Achilles was probably about the size of today's 6th grader.

Those small helmets could well be armorer’s models made to display the maker’s craft.
