| -2- (d) Merlin Engine Sparking Plugs. We have now completed further engine tests on the Lodge X465D/3 sparking plug submitted to us for test as a result of the poor performance of the X465D/1 on the last type-test, and the plugs are available for inspection at our Works. It might be to our mutual advantage if you visited us to discuss the future of the Lodge Plugs for the Merlin engine. Yours faithfully, FOR ROLLS-ROYCE LIMITED. (handwritten) X6002 a | ||
