Date 21 April 1936. DIRECTORS: J.{Mr Johnson W.M.} ALFRED HOPPS BERNARD HOPPS ALEC M.{Mr Moon / Mr Moore} LODGE F.{Mr Friese} BRODIE LODGE All letters must be addressed to the Company, not to individuals Dear Mr. Robotham, I hope to get delivery of my 4¼ litre Bentley in a few days time. Would you please let me know if it is desirable to run this car in quietly, and what distance is required to run it in and what is the maximum engine speed which it is safe to use during the running-in period. Would you recommend the use of upper cylinder lubricant mixed with the petrol, and is there any particular brand you recommend. I take it you do not recommend the use of graphite mixed with the upper cylinder lubricant. With kind regards, Sincerely yours, Bernard Hopps. | ||
