IN YOUR REPLY PLEASE REFER TO Sales DEPT AND QUOTE REFERENCE LMB/KS 9th May 1919. "For the attention of Mr. Hives" Messrs. Rolls-Royce, Ltd., Nightingale Road, D E R B Y. Dear Sirs, We have devised a special Cleaner for use in connection with our standard "R" types of plugs, and we have much pleasure in sending you herewith one dozen of these - the application of which is exceedingly simple. The plug is held sparking points upward - the Cleaner is then placed over the central electrode - pushed right home and then gently rotated a few times. This will then have the effect of removing any carbon deposit which may have accumulated without injuring the internal insulation of the plug. Yours faithfully, p.p.
