| [Handwritten:] X4040 [Stamped and struck through:] TO R.H.C. C. EFC. {E. Fowler Clarke - Electrical Engineer} BY {R.W. Bailey - Chief Engineer} /RD3/ML1 3.3.28. BATTERY CHARGE CONTROLLER. (R'S.GREEN LAMP SCHEME). Will you please put in hand 2 units to D.71542 L.O.P., this unit embodies many parts previously issued on controllers and the only new parts required are sent herewith:- D.71536 - Base Plate. D.71540 - Resistance Coil. D.71543 - Contact Holder. We attach blueprints of these parts and a diagram of the connections for this unit. We have ordered one Warning Light with a green glass from Lucas's if they can supply it and we do not propose to alter the engraving on the switchbox at the moment, we think that when there is a chance of the unit being standardised something should be settled in conjunction with Sales.
