During WWII they converted vehicles for war work. It was in 1950 that the firm entered the field of light fabrication, a move that was to play an important role in its history. In 1952 they started building tractor cabs after a request from a local farmer to create somthing to protect his tractor driver from the worst of the exposed Downland weather. The Lambourn tractor cab was born! Lambourn’s engineers devised a simple light structure, and it was not long before new designs were ready to fit the most popular makes of tractor - Fordson and Ferguson. A simple design of a canvas top over a light steel frame suited the company’s existing manufacturing operation and had the great advantage of being much quieter in use than tin panels which tend to vibrate.
