In order to be able to change a valve spring quickly we want to make the air silencer easily detachable on Hall's car. The best way of doing this we think is to raise the silencer as on the streamlined car and have easily accessible nuts holding it down. The attached sketch from Jenner gives an indication of what is required. Ha/Rm.{William Robotham - Chief Engineer} | ||
