Lee Han Seng was one of Singapore's more successful racing drivers. His early career consisted mainly of Lotusseses, including this very pretty red 23. He took victory in the 1965 Singapore Grand Prix at Thompson Road in this car.
His later acquisition, a Porsche 906, is also included in the WSC 60s mod.
