| Y4305 To RR of America Inc. from R. {Sir Henry Royce} For the attention of :- Mr. Belnap, Mr. Olley, Mr. Nadin. R1/M10.2.22. c. to CJ. BJ. c. to PN. {Mr Northey} Hs. {Lord Ernest Hives - Chair} c. to Ry. EP. {G. Eric Platford - Chief Quality Engineer} c. to Hm. {Capt. W. Hallam - Head Repairs} X.4305. X.4390. X.3923. My car has been fitted with starting and running equipment similar to the scheme we have recommended as standard for the Springfield production. This comprises the exhaust heated throttle (instead of water heated) and the revapouration scheme with interceptors, and the small starting carburetter with a moving throat. This car is running in our coldest weather here quite satisfactorily on the poorest petrol we can buy, with 20% of ordinary kerosine added. It is now going to be run across France where the temperature inland is very cold and we have every confidence that its behaviour will be satisfactory. X.607. In conjunction with this car it has been noticed that the recently supplied Exide batteries with ebonite separators (as well as wooden separators) do not give such a large starting current owing to the increased internal resistance compared with those used before the way, but are much more consistent in their behaviour; the pre-war ones were very liable to internal shorts, which ran down the voltage, and caused starting failures.
