Query: Good primer on the M8 and M20

I like the Osprey series in general in this book in particular. Like other Osprey books, this volume gives a brief history of the weapon's development, it's specifications and modifications through it's career, a lot of good pictures and accurate color artwork, and even a first-hand account of the weapon's effectiveness in combat.It's a good, short primer on American armored car design and employment during WWII. The only thing I do not like is that these nice little books are still a bit overpriced for their length. I recommend it in spite of this small flaw.
