| X. 4195 To HS{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} DAG/CB23-11-20. Re Battery in Frame. Attached is a print of "N" Scheme 619 shewing method of mounting the battery in the frame on the armoured cars. This scheme is not standard and there are no parts available, but it might serve as a guide to America if they could obtain a battery of similar dimensions to our standard.
