Diecast Masters are launching an entirely new concept, the Caterpillar Evolution Series.

This Evolution Series scale models pay a homage to the rich history and remarkable sweep of earthmoving technology, from the earliest Caterpillar Earthmoving equipment to the most recent.

Diecast Masters brings together old and new Caterpillar machine models. Along with the scale models, each package also holds a richly illustrated book that tells the evolutionary story, from the machine of the past up to its modern counterpart.

The Evolution Series models are mounted on special bases and placed in quality flip-top packaging, protected by a black outer sleeve. A full color detailed 44-page booklet, included with the scale models provided with period-accurate colors and decoration details & era-specific operators, traces machine evolution in words and pictures.
