To Roy.{Sir Henry Royce}

Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems}28/JH.9.4.37.

We thank you for the sample pump from the S.U.Co. We should like to point out that it is not fitted with C & A washers but withnthe old type cork insert plugs which were discarded.

It is necessary to have plugs without a recess for the C & A washer and we have asked for these.

A standardisarion sheet will be issued for C & A washers when 35-EX completes its 10,000 miles.

We do not consider it necessary to have the bottom plugs plated as they are not visible that is if any saving in cost would be effected.
