I read this book, here in Brazil.I'm an agronomist and I like to read books.
This book is concise and has many B&W photos.This book is also correct.The author seems to be from England, but even so, all failures from the sub-machinegun Sten, are described in this book.This book is unbiased.
The biggest failure of this book is that, it hasn't anything about hand-grenades,rifle-grenades, bazookas and panzerfaust.This book is about pistols, revolvers, rifle, sub-machineguns and machineguns used in World War II.
This book is incomplete, but concise and correct.
