Dear Sirs, You will recollect that you recently supplied us with three types of plugs for further test on the Bentley, two of which were of aero construction, one stellited, and the other type was the X.335 with the copper flush with the bottom of the insulator. We are at present running these plugs in France, but should like three more sets of seven each, so that we may carry out investigation work in parallel on our cars in Derby.
