"Helmets and body armor in modern warfare" online

You may already know this, it is an online source with the complete text of this book printed in the 1920s. They did not preserve the text formatting, so it looks confusing at first. The table of contents is a bit further down.

Helmets and body armor in modern warfare

That is an excellent book. Dr. Bashford Dean also helped design many of America's experimental helmets as well.

Joe mentioned this book here some years ago. The book is also to be found in Adobe pdf-format, scans of the original pages, with the most interesting photographs. An amazing book it is.
