| 8540. 23941 C.H.Hancock Esq., Hotel de France, Chateauroux, Indre, FRANCE. From Ha/Rm.{William Robotham - Chief Engineer} Ha/Rm.{William Robotham - Chief Engineer}5/MJ.21.7.31. We are awaiting with interest your reports on the shock absorber loading required to give stability, and on the effect of the various tests we proposed on the burning of your exhaust valves. Sg.{Arthur F. Sidgreaves - MD} has decided that the 25 HP. shall not go to France until it has the correct radiator on it which will be one inch higher at the bottom than at present. We are going to work the holidays on this item, and should get it away in about fourteen days, but we will let you know something further as soon as possible. With regard to 25 -EX. We are sending out some improved torque reaction arms today, and shall follow on with some pieces for controlling the radiator and bonnet which will be suitable to go into production if you consider that they are satisfactory. We shall let you have all the pieces which have been suggested and you can then select what you want. Ha/Rm.{William Robotham - Chief Engineer} | ||
