context_page_description: Deep Sanderson is a brand of racing and sports car that was manufactured in Britain. The cars included a series of single-seater racing cars and small sports coupés built and raced mainly in the early 1960s, although the name was also associated with other projects. The last Deep Sanderson was built in 1986.
context_section_description: In 1963, Lawrence inherited a project that was originally meant for Downton Engineering Works but which they were unable to undertake. Downton had convinced the client to have a car built with two engines, similar to a Mini that John Cooper had built earlier, but this one was to be a single-seat hill-climb car. Lawrence took on the job but built the car as simply as possible, installing two 1071 cc Downton-tuned Mini engines and their transaxles in a minimal chassis with a Mini subframe in the front and a Deep-Sanderson cross-member and suspension in the back. Designated the DS105, and nicknamed the "Twinny", the car debuted at Brands Hatch on Boxing Day 1963. The car raced again on Easter Monday at Mallory Park 1964. By this time a new linkage had been added that allowed the driver to vary the throttle opening between the engines, giving controlled oversteer or understeer or neutral handling as needed. The only problem was that the brakes were not up to the stresses imposed by the two engines. The car was entered in Sidney Allard's "Festival of Speed", where it performed well. It was then sold to John Pearce with the understanding that it was being resold to the United States, but this sale was never completed. The next owner was Duncan Rabagliatti.
