| To Wd. {Mr Wood / Mr Whitehead} from EFC. {E. Fowler Clarke - Electrical Engineer} X4617E EFC {E. Fowler Clarke - Electrical Engineer} 1/T5.6.25. X.4617E. EXPERIMENTAL EXIDE BATTERY. 40/50. Reference our EFC {E. Fowler Clarke - Electrical Engineer} 7/T23.4.25, we have now received the two single P & R RR.11 cells in good condition. We should be pleased, having somewhat altered our programme, if you would order one further similar cell. We should how also like to knew the up-to-date prospects of receiving the Exide 6RR5/1 battery made up with alternate cells having triangular grid bars with their apices facing inwards and outwards respectively. It will be remembered that we want to receive this battery in a dry condition. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
