| 800b To Sg.{Arthur F. Sidgreaves - MD} from Rm.{William Robotham - Chief Engineer} Rm.{William Robotham - Chief Engineer}14/JH.24.1.40. With reference to Sg.{Arthur F. Sidgreaves - MD}1/E.23.1.40. I believe the car you refer to is dark green, and is 3.B.50. It represents the Silver Dawn in all but the radiator. This car has been used for development work for the past six months and in consequence is now fitted with a number of experimental features, some of which are open to criticism. However, we will make the car reliable and arrange for it to be at Duffield Bank House by 8.15 a.m. on Wednesday. Rm.{William Robotham - Chief Engineer} | ||
