| 86089. Hs{Lord Ernest Hives - Chair}/Wst.1/MA. 19th January, 1934. The Edison Swan Electric Co.Ltd., 23, Goldsmith Street, NOTTINGHAM. Dear Sirs, Replying to your letter of the 18th instant reference WN/FA. we are not particularly interested in the ordinary V filament 48 watt and 60 watt lamp bulbs but in a new 48 watt V filament lamp bulb which has the same luminosity as a 60 watt bulb. This lamp bulb has been produced for Messrs.Lucas by another lamp bulb manufacturer and will be supplied to us on all the headlamps for the Bentley chassis. The life of the bulb is reduced somewhat but Messrs.Lucas state that they will last a lighting season without replacement. Have you any knowledge of this bulb and could you supply us with replacement bulbs when required? Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
