| To EFC. from R.{Sir Henry Royce} Copy to CJ. ORIGINAL. R3/G26/4/19. (2) X.3129 - WIRING TUBE FOR BATTERY IGNITION HIGH TENSION WIRES - 40/50 H.P. CHASSIS. X.3474 X.1520 With reference to the above, I agree that it is suitable for non-trembler ignition, but - (1) have we proved that earthing wires are necessary ? ✓ (2) have we tried modifications of wiring or condensers to improve trembler ignition on cars which have not electrical starters ?
