| Enclosure. X.4292 Dec: 8th. 1920. E.{Mr Elliott - Chief Engineer} Fowler Clark Esq. Rolls Royce Ltd. Nightingale Road, Derby. Dear Mr. Clark, I wish to thank you for your letter of the 7th. inst. I am very much obliged to you for putting the Cigar Lighter before your Sales Department and would say that the Car Heater is intended to be used on the electric lighting mains and not off the accumulators. The wattage is about 60-100 watts. These heaters can be made up for any voltage to suit the circuit of the garage. Very sincerely yours, J.{Mr Johnson W.M.} Milwain | ||
