| To CJ. from R.{Sir Henry Royce} -4- R10/G22/7/21 Contd. Judging from this, if the Delco switchbox is adopted, and the Delco buzzer, it looks as though the Delco should also make the distributing board. I do not think, however, it is a very serious matter whether satisfactory fuses (in carriers of the R.R. type) made of copper wire or a buzzer is used. Apparently the buzzer could only be in the circuit as shown in the wiring diagram* attached, whereas the fuses can be in any circuit it is desired to fit them.
