| (2) when taking down the gearbox, and also an additional safety. RADIATOR. Regarding the radiator it was decided that there was such a substantial difference in the cost of a wavy tubed radiator and our proper honeycomb radiator, in matrix materials, that the crinkled tube type should be used on Bensport. Judging from the 4 litre Bentley radiator at present at CamachaHenry Royce's office in West Wittering it would seem to be a most illogical, costly, design which I am very pleased we have not got on RR. cars. EV.{Ivan Evernden - coachwork} tells me that after all the discussion between coachbuilders, Sales, and others, it has been decided that the RR. radiator and bonnet pieces up better with a closed body than any other form, and that the coachbuilders do not like the Bentley pattern because of the difficulty of the large radius of the shoulders of the bonnet and radiator. RADIATOR SUPPORT. It was also arranged and agreed that the radiator should be supported on trunnions direct on to the frame. This may cause a little extra weight in the radiator itself, and will make it impossible to have central support, but will we hope fill the requirements in the simplest way. CARBURETTER. The situation of the carburetter is such that it is impossible to use the SU. ugly type of disc silencer, and it requires some drawing before it can be accurately ascertained how the carburetter, undershield, and brake ropes can be made to clear one another. In the new front axle the brake rope centres are moved out to 8" at the axle. FRONT AXLE & CROSS STEERING TUBE. Owing to the crankchamber being the lowest point, which however is not excessively low for this type of car (7.5") we found it was necessary and possible for the front axle and cross steering tube to be dipped in the centre another .5". We do not think this modification to the axle will be objectionable in Peregrine or Bensport because to maintain an economical production and spares programme these two front axles should be alike.
