| To Hs.{Lord Ernest Hives - Chair} Y4239 BY/SS{S. Smith}7/DB.{Donald Bastow - Suspensions}8.1.24. RE 20 HP CHASSIS - CONTROLS - RIVETTED PINS. In looking into the matter of annealing the steel hollow rivetted type of control pin, we are of the opinion that the life of the bearing portion would suffer. Mr Bailey would like you to submit samples of these pins made in Bz/PD, and rivetted over into a std: lever. E.50657 would make a good sample. As this matter will affect the immediate production, will you please produce these parts as soon as possible. BY/SS.{S. Smith} | ||
