I understand that you have had considerable experience of the behaviour of the Minx Box in the 14 h.p. Hillman chassis and that some failures have been experienced. To the best of my knowledge, the transmission used in the 14 h.p. Hillman is identical with the Minx but made of somewhat better material. As we are proposing to use a box of much the same size coupled to a 14 h.p. engine, any failures which you have experienced would be of the greatest interest. If possible, we should also like to have the failed pieces so that we can get the material analysed. Rm.{William Robotham - Chief Engineer} | ||
