| X4538 To Sg.{Arthur F. Sidgreaves - MD} From Hs.{Lord Ernest Hives - Chair} c. to Wor.{Arthur Wormald - General Works Manager} Hs.{Lord Ernest Hives - Chair}5/MJ.18.12.31. 20-G4. CAR. The fact that this car weighed over 35 cwt. without passengers, and also that it had a higher axle ratio, would account for the difference in acceleration as low speeds. If any duplicate bodies to 20-G4 have been ordered an effort should be made to keep the weight down. At the present time the car is heavier than a six seater. Hs.{Lord Ernest Hives - Chair} | ||
