Field Marshall Series 3A

The Field Marshall Series 3a was built from 1952 to 1956 approx 2125 were produced. These tractors had several improvement over the Series 3 one of which was a revised piston ring set up the fire ring design. Some early Series 3a were painted in the familiar Marshall green but later were painted in the Fowler orange. The Field Marshall Series 3a was the last of the iconic single cylinder design made by Marshalls of Gainsborough. By the early 1950's Marshalls had strong compertition with more modern designs and found it hard to compete in the home market, although sales abroad held reasonably strong.
