Colin Robin and Jon Skillet met in 1973 and started their sprint experiences on an old Triumph 650 which Jon had supercharged. However, Jon saw a twin-engine BSA sprint bike in a magazine and suggested to Colin that they could come up with something similar. So they acquired some bits and pieces of other bikes and began the build. The Obliterator on a good day Jon had previously owned, then sold, a BSA Spitfire but it got wrecked and he managed to get parts from this bike.
