| To EFC. from R.{Sir Henry Royce} Copy to CJ. ORIGINAL R10/G12/7/21. X.3082 RE 40/50 H.P. STARTER MOTORS. X.4276. I consider that all starter motors for the 40/50 HP. should be wound with coarser field copper, so that the motor runs faster, takes more battery current, and turns the engine faster. We have arranged that they shall do this on the American made chassis with the improved Bijur motor. Kindly get an experimental one fitted for, say, 25% increase.
