| Contd. -2- RL/M20.12.21. tried failed. Therefore it shews that with the ordinary small bayonet lamp-holder for double wiring, low voltage, and large C.P. lamps should be avoided as absolutely disastrous to reliability, and how much better single contact ought to be if advantage is taken to make the single contact more robust, as it is so easily possible. Hence I am pleased also for this reason we are adopting single circuit wiring. R.{Sir Henry Royce} | ||
