| 6066. May 21st.1937 Rm{William Robotham - Chief Engineer}/Wst.3/AP. Messrs Joseph Lucas Ltd. Great King Street, BIRMINGHAM 19 Dear Sirs, Re. Lucas Electric W.T. Horns. We should be glad if you will arrange to supply all our new type horns with the vents on the trumpet flare to prevent the formation of snow blocking the orifice. Whilst we have proved that this does not assist us with regard to the failure of the horns in heavy mist and rain we consider it is an advantage where snow is encountered. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
