Typical of American designs in use since the 1920s and includes a detailed stationary diesel power plant, walking beam, rear crank and counterweight, along with the odd-shaped "horse head" front counterweight that gives the machines their nickname 

Designed from the ground up to be a WORKING model, the kit includes a hidden drive. Whenever you're ready, just add the Universal Gearbox and Motor Drive Kit #933-1050, sold separately, to power your pump. 

Complete instructions and precise engineering produce a great looking, easy to build replica.
