| X3700 Expl: Dept: Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}3/LG. 31st. May 1927. Messrs. The Zenith Carb. Co. Ltd., 40-42 Newman Street, London W.1. Dear Sirs, We have received the petrol filter which we sent to you to have an element with a larger filtering surface fitted. We find the one that you have returned has a larger gap between the plates instead of the same gap between the plates, and a larger outside dia. of disc. The filter that we have just run 10,000 miles in France had the original gap of about .002" between the plates but a larger dia. of disc than originally supplied. We should be obliged if you could let us have a filter fitted with this type of element when we will return the one which you have just sent us, which is of no use to us. Yours faithfully, | ||
