Manufacturers and Agents used to be supportive of Shows and similar events, I have a number of Ransome Ploughing Match Certificates and engraved glasses awarded to Prizewinners.
The Certificates were awarded to L Dixon,who I found out was Les Dixon who was British Champion in 1952 and 1953,would also have been champion in 1951 but after finishing ploughing his father screwed down the rear wheel which was reported and by strict interpretation of rules Les Dixon was disqualified.The Dixon family were all ploughmen from horse then tractor ploughing over three generations they won a total of 786 Championships.
