Production Period: 1956-1957

The first of the Caterpillar Bulldozer model in the No. 18 series. Model derived from the No. 8A Caterpillar Tractor with an added bulldozer blade.

Production Period: 1958-1960

Model of a D8 Caterpillar. The casting includes "No. 8" on the base indicating that the body is the same as that used for No. 8 - the Caterpillar Tractor. Note that the No. 8 Caterpillar Tractor (shown below along side of the Bulldozer) includes the pivot pin for the blade.

Production Period: 1961-1963

A somewhat larger model of 8B (2 1/4" instead of 2").

Production Period: 1964-1968

A somewhat larger model of 8B (2 3/8" instead of 2 1/4"). The casting is different from 18A and 18B as it
does not include the driver.

Production Period: 1969

Interesting model based (loosely) on the International Harvester Scout.
