Agricultural Tractors at the BWLR
The Field-Marshall tractors were manufactured by Marshall, Sons & Co. of Gainsborough, Lincolnshire, England.
The Marshall, a single cylinder tractor, was first produced in 1930. During WW2 the factory reduced tractor production due to being engaged in the war effort and in 1945 Marshalls introduced an improved tractor and henceforth called them Field Marshalls.
