| contd :- -2- Another [STRIKEOUT:admirable] improvement which in our opinion is a definite advance is the torque control to the front axle. The increased safety with this fitting is worth a lot. We know ourselves of the number of accidents which have been caused entirely by the absence of the torque control on the axle. When the torque control is fitted, we are then free to fit weaker front springs if they are proved [STRIKEOUT:desirable] for comfort. Another feature which I am sure will be greatly appreciated by customers is the proposed central oiling scheme. As we have now all the instructions for this at Derby we should be able to get this on a car quickly. It is thought desirable that a new chassis should be built up with the central oiling scheme. We therefore recommend that on this new chassis we should have the following new parts and that it should start on a 10,000 miles test for the usual standardisation. (1) Turbulent head in aluminium. 4.24 comp: ratio. (2) Pedestal pistons - single bolt type. (3) Perfect circle scraper rings. (4) Improved rockers to avoid side thrust. (5) Modified exhaust system which also does away with the choke valve in the exhaust pipe. (6) Central oiling scheme. (7) New serrated coupling for clutch. (8) Torque control for front axle. (9) Front springs made in Silicon Manganese, and modified clip. (10) Narrower and lighter radiator with integral shutters. (11) Spare wheel carrier at the rear. contd :- | ||
