Rolls-Royce Ltd., 14-15, Conduit Street, W.1. X.2544 Dear Mr. Johnson, The subject of Valve Stem Lubrication of your post-war models is no doubt receiving your careful consideration. In this connection, I beg to call your special attention to the "DUCO" Valve Stem lubricator, and would like the opportunity of sending you a set free of cost so that you can test them either on the road or bench. A leading Manufacturer gave them a thirty-eight hours' bench test with good results - see last leaf but one of enclosed booklet. I attach a special measurement form. Please fill in and post to me. Yours faithfully, BROWN BROTHERS, LIMITED. Managing Director. [Footer, upside down] R.R. 235A (500 T) (S.D. 408. 26-4-17) Bm. 2/156/13. | ||
