| X4335 To BY {R.W. Bailey - Chief Engineer} /RD. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 1/T19.10.27. Will you please instruct two sets of battery ignition contact points in the same material, viz. gold-silver, which we use for the cutout contact points, as it has been suggested to me that I should find this would go quite well.
