To EFC. from R.{Sir Henry Royce}
8th March, 1919.
R4/G8319.
X.3362 RE AMMETER.
I do not think the ammeter belonging to the Liberty ignition would be suitable for the little switch-board here. I should be glad if you would get me a permanent magnet moving coil type, central zero, and a maximum readying of 30 amperes, Weston make.
