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.

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.
