| [Handwritten]: 600a CHATEAUROUX. Rm{William Robotham - Chief Engineer}/IMW{Ivan M. Waller - Head of Chateauroux}/4/JAB.28.37. [Handwritten checkmark/initials] To. Rm.{William Robotham - Chief Engineer} 26.G.VI.- 25/30 HP. I beg to confirm my telephone conversation with you this afternoon re the following points. 1) Raised Front Engine Mounting. The raised cross member is broken right through on the offside curve. The cast aluminium bearer attached to the cylinder block has broken off inside the rubbers. It is hollow and the section seems too light for the job. It appears to have been cracked for some time. [Handwritten]: 1/P/P3 re aux parts 2) 2) Front Hub Tool. A tool is required for the first ring. This has nine serrations against six on the Bentley. 3) Front Tyre Wear. Very bad flats have worn on the O.S.front tyre and the N.S.front is also unevenly worn. We cannot exactly say what the cause is at present, but suspect lack of buffer clearance combined with uneven braking. We have removed the tyres and are keeping them for your inspection when you come out. 4) Petrol Supply System. We are working on the following lines, the system fitted to the car having suffered from starvation troubles. a) Shortest possible length of pipe under the bonnet, as straight as possible with a steady rise. b) Petrol pumps in coolest place available. c) Petrol filter close alongside pumps. The tap argument against this does not hold good as in standard position the syphoning trouble occurs just the same way if the petrol level in the tank happens to be above the filter, as can easily be the case. Moreover a tap would be useful in any case when the pumps are removed. d) Restriction on suction side of pump must not seriously reduce maximum free flow. We will wait till we have proved our layout in hot weather before giving full details. ------------ Rm{William Robotham - Chief Engineer}/IMW.{Ivan M.
