| -2- Rm{William Robotham - Chief Engineer}/swdl.{Len H. Swindell}15/JH. 30th. November, 1938. N/MC Although the drawings of our seats sent to you are more up to date. (e) small locking slots in the periphery of the seat into which the alum head is peened are of course a safety factor, but we consider that if the conditions of the seat and fitting are correct, this procedure is not necessary. Hoping the above will be of assistance to you. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
