| x967 COPY OF LETTER RECEIVED FROM PRICES PATENT CANDLE CO.LTD. 18th. January, 1934. Messrs. Rolls-Royce, Ltd. DERBY. YOUR REF: ROY{Sir Henry Royce}6/MG. Dear Sirs, As promised by the writer when he had the pleasure of visiting your Works earlier this week, we give you as undernoted viscosity and other figures for Motorine C, Motorine D, and Motorine E.{Mr Elliott - Chief Engineer} You will recall the writer's information that the last mentioned was introduced specifically for Model T. Fords. When these, in course of time, disappeared, we had no further market for Motorine E, and this grade was withdrawn from our lists. In consequence this is not stocked by Motor Traders. It was, and is, an excellent lubricant on the lines of Motorine C, but much lighter in body. and in consequence we have retained it so that it can still be supplied to order. In the hope that this letter will afford the information desired, We are, Yours truly, PRICE'S PATENT CANDLE COMPANY LIMITED. MOTORINE C.
