| x4275 To EFC. from R.{Sir Henry Royce} R3/M15.9.25. X.800 X.4357 X.8690 X.4275 In our H.T. distributors I believe we use nickel. Would any other metal be more suitable such as tungsten, real silver or stainless steel ? Looking at the Bosch distributor head it would appear that their insulation is considerably less than we use, and yet you are complaining of tracking of the same materials. R.{Sir Henry Royce} | ||
