| X1812l. HS {Lord Ernest Hives - Chair} 5/LG 26th. Nov. 1921. Geo. Roberts Esq., C/o Peak Frean & Co.Ltd., Drummond Rd., London S.E.16. Dear Sir, Attached herewith is our report on the Prima Sparking Plug. We regret that there has been delay in testing these plugs but it has been necessary to run these tests in conjunction with other Experimental Tests. You will realise that it would be far to expensive to run an engine or car especially to test six sparking plugs. Yours faithfully, | ||
