| To Wor.{Arthur Wormald - General Works Manager} From Hs.{Lord Ernest Hives - Chair} 84117. Hs.{Lord Ernest Hives - Chair}2/MJ.3.2.32. COMPLAINT OF MR. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} DUVEEN - 56-GX. CAR. We should expect that H.{Arthur M. Hanbury - Head Complaints} corrected Mr. Duveen's criticism of 56-GX. This car is a standard car and therefore Sales should have sufficient experience to be able to justify our arrangement. The chief point is that we do not rely on water temperature for heating our carburetter. We have exhaust heating, and we claim that this makes us much more independent of the water temperature than any scheme for adjusting the thermostat. In the case of the Humber Snipe, we agree that they have an adjustment for the thermostat, but on that car they rely entirely on water heating for the carburetter. As regards the complaint of having to use the starter carburetter for starting, it will not make any difference to this feature if the engine is 60° instead of 50°. We should quite expect the difference in starting between the Humber and Phantom 11, but no adjustment of the shutter will alter that feature. On our original tests of thermostat shutters, this question of water temperature was discussed at great length. The Expl. Dept. wished to fit a spring in the thermostat in order to increase the normal temperature but R.{Sir Henry Royce} was very definitely against this and we could not make out a sufficiently strong case to convince him. It is a very easy matter to fit a spring to Mr. Duveen's thermostat so that his normal temperature will be round about the heat of 80° instead of 65°. If Sales will let us know, we can arrange to send the spring to Cricklewood with instructions of how it should be fitted. Hs.{Lord Ernest Hives - Chair} | ||
