| To Hd.{Mr Hayward/Mr Huddy} X5080 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}15/KW.12.10.34. We are sending to you an air valve which was removed from Mr. Cowen's car and replaced by an experimental valve. This air valve is of no interest to us as it is standard. We presume it will have some value as a spare to your Department. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
