Item # 597314
May 16, 1908
SCIENTIFIC AMERICAN, New York, May 16, 1908 

* Early form of the tank 

The front page is taken up with two photos of: "A Curious Means of Propulsion - The Caterpillar Motor, Showing the Weight-Carrying Wheels". Although a novel concept at the time, this dates from the introduction of the caterpillar-type means of movement, adopted not only by the construction industry but the military as well. More photos and text on page 4 (see photos).
Twenty pages, nice condition.
