| X4117 PN.{Mr Northey}3/WT1.10.31. S/W. Hs.{Lord Ernest Hives - Chair}.. from PN.{Mr Northey} Copy to Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} ER. GX. By.{R.W. Bailey - Chief Engineer} Lord Cholmondeley. Chassis GFT43. Now that it has been decided that our hydraulic dampers on this chassis shall be reinforced by a set of adjustable Hartfords, front and rear, and that the fitting of these Hartford shall be carried out by Messrs. Andre in London, in accordance with the scheme submitted by them, and which we have definitely approved in this case, By, will doubtless arrange for the stronger springs having the less buffer clearance to be fitted to the chassis. I have informed Messrs. Andre that the chassis will be available for them at their Works in about a week's time in order that they can carry out their job which will take a couple of days. In view of this chassis, when the special streamline is fitted to it having to conform to a specification of performance in respect of maximum speed which is higher than our standard, Sg.{Arthur F. Sidgreaves - MD} insists that it shall be ascertained definitely that our efforts to fulfil conditions of the specification shall be known and proved by a test at Brooklands before any expense is gone to, either in connection with fitting the Hartford dampers or the body, in order to reduce any contingent expense in the event of our failing to achieve the results required. I shall be glad therefore if you will arrange for someone from your Department to meet me with the car at Brooklands directly you are ready, in order that this test can be carried out. I am aware that much of the success of our efforts will depend upon the effective streamlining of the body now under construction, and that probably the best line you can take is to rig up on this chassis a body which in your opinion conforms as near as possible to the wind resistance at say 70 m.p.h. of the body under construction, a drawing of which I attach for your information. Please note that this drawing should be returned in course of post because it is required to show to the owner shortly. CSAL | ||
