| To Rm{William Robotham - Chief Engineer}/RC.{R. Childs} from G/Rb.{R. Bowen} G/Rb.{R. Bowen}1/A/R.16.9.38. Re: Ignition Coil D.75673 and Ballast Resistance DW.296. Rm{William Robotham - Chief Engineer}/RC.{R. Childs}6/JH.12.9.38. Kindly note the present factory cost of the parts to which you refer is as follows:- Ignition Coil D.75673 11/9d each. Ballast Resistance DW.296 2/10 " It is understood that when the proper die for the Coil Case is available, the factory cost of the complete Coil will be subsequently reduced to 10/0d, but the cost of the Ballast Resistance will remain as stated.
