I have a paperback that I just happened to notice as I passed by the bookstand at the market, years ago.
You gotta love finds like that, completely out of the blue and unexpected!
It's titled: "Secret Weapons of World War II" by William Yenne (Penguin Books 2003, ISBN 0-425-18992-9) and covers a broad range of weapons of both the Axis and Allies. While it's only 290 pages, it touches on an amazing range of "wonder weapons" with a brief overview at the head of of each chapter, and great details of the weapons in each.
There aren't any photographs, but the author has gone to alot of effort to weed out fiction from fact, and is a great read!
