The M41 Walker Bulldog was a light tank developed after World War II, going into service in 1955. While the US never took it into battle, a few of the countries it was exported to did, notably South Vietnam, where it was the main tank until they got M-48s.
This softcover book covers the subject in many full color detail photos and several drawings. If you are modeling one of these and want to know what the final drive adapter drain plug or the turret ammo storage area looks like, there are a picture or two included.
This book is ideal for all you super-detailers out there, and pretty much every square inch of the vehicle is covered. The pictures are all of several preserved/restored examples, so are pretty much in very clean condition.
