Rolls Royce, Ltd., Nightingale Road, DERBY. Dear Sirs, For the Attention of Mr. Fowler Clarke. Reverting to the interview which our Mr. Lawrence had the pleasure of having with you on the 13th inst., we have been into communication with our Works people on the question of grades for your control brush. They inform us that they would be pleased to send a few samples in "EG30" & "EG60" qualities, so we should be pleased to hear from you how many you would like them to send to enable you to carry out the necessary test. They understand that the "EG30" quality carbons forwarded to you on the 14th August last were probably for the main circuit but a test of this grade would none the less be very interesting and we shall be pleased to hear from you further in the matter. In thanking you in anticipation, we are, Yours faithfully, For Le Carbone. T/B FM1612. | ||
