| γ 461r. To Wor.{Arthur Wormald - General Works Manager} From Hs.{Lord Ernest Hives - Chair} Hs.{Lord Ernest Hives - Chair}8/MJ.16.2.33. With reference to the attached. As it would appear that we may for sometime be producing brake drums in cast iron, we may consider obtaining one of the special furnaces to produce this material. We shall also expect with these new drums to have a reduction in service charges on brakes, which should be taken into account. The front axle control will inevitably increase the cost, but we are hoping there will be a reduction with the new type shock dampers.
