| X4288 To D/BP. from EFC. EFC6/T1.1.24. With reference to the attached, all our batteries are either experimental or duty batteries required in the Expl. Dept. and we have no more of the latter than are necessary for the service required. Therefore it appears that two standard 40/50 Exide batteries should be booked out and specially allotted to this job. EFC. 'N' Repair Depot. | ||
