| To C.J. from R. {Sir Henry Royce} -2- R12/G15/2/21 Contd. me, but I found it definitely less expensive, and ran my car more perfectly than anything else, i.e. starting good, no detonations, m.p.g. good, distribution good. Now I must, (as soon as we have made the modifications), try to use a mixture of petrol and lamp oil so as to be like the Americans. R. {Sir Henry Royce} | ||
