In connection with the electrical work of the Chassis Division and more particularly on wireless work, we are badly in need of one of these oscillographs. We have had the instrument on test and found out that it will do what we require. The whole equipment will be invaluable for the new noise analysis project which we propose to undertake when we come to the cars with Monocoque construction. Therefore, we should be glad if you agreed to us purchasing the apparatus tabulated below:- Cathode Ray Oscillograph. £30. 0. 0. Piezo crystal pick-up. £7. 10. 0. Rm{William Robotham - Chief Engineer} Agreed. HS{Lord Ernest Hives - Chair} | ||
