| Oy file. Expl. Dept. Ha/Rm.{William Robotham - Chief Engineer}1/MJ. November 19th.1931. M.Olley Esq., Cadillac Motor Car Co., Detroit, Michigan, U.S.A. Dear Oy., At the risk of inducing you to waste far too much of your time corresponding to Derby, I would ask if any recent improvement has been made in the States on Bijur drip plugs. Every time we strip a car after an endurance road test of ten or twenty miles, we find quite a lot of these plugs completely blocked up and we believe it is largely due to the felt filters. If you have not time to write about this item, you might store the information up until I see you. Yours sincerely, | ||
