Doug (LD) Serrurier was a South African speedway champion before becoming one of the country's top single-seater racers in the 1950s and 1960s. He began building chassis when the local automobile club announced that it was going to hold a four-race winter series in 1961-62. The first LDS was a copy of a Cooper and appeared for the first time at Kyalami in December 1961 with Fanie Viljoen driving, while Serrurier himself raced a Cooper. Viljoen beat Serrurier and there were three LDS 1 chassis at the second race a few days later at Westmead. One was crashed in practice and did not race. Three of the cars appeared at the non-championship South African GP in East London on Boxing Day but they were outpaced by the imported machinery.
