| X.3398 To Mr. Bowering. (Demonstration School). EFCl/T23.9.24. X. 3398 - PETO & RADFORD BATTERY: Unless it has failed, or has been changed for any reason, you should have a Peto & Radford type BDT.11 battery on your School car 7-LW, which was originally an experimental battery and possibly labelled with a figure 4. This battery was put on 7-LW on 15.5.23. If this battery is still on the car we should be interested to know if it is still satisfactory, and if or when you require a new battery (which now you should get from stock) we should like to have this back for opening up and inspecting the condition.
